# Configuration file for jupyter-notebook.

c = get_config()  # noqa

#------------------------------------------------------------------------------
# Application(SingletonConfigurable) configuration
#------------------------------------------------------------------------------
## This is an application.

## The date format used by logging formatters for %(asctime)s
#  Default: '%Y-%m-%d %H:%M:%S'
# c.Application.log_datefmt = '%Y-%m-%d %H:%M:%S'

## The Logging format template
#  Default: '[%(name)s]%(highlevel)s %(message)s'
# c.Application.log_format = '[%(name)s]%(highlevel)s %(message)s'

## Set the log level by value or name.
#  Choices: any of [0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL']
#  Default: 30
# c.Application.log_level = 30

## Configure additional log handlers.
#  
#  The default stderr logs handler is configured by the log_level, log_datefmt
#  and log_format settings.
#  
#  This configuration can be used to configure additional handlers (e.g. to
#  output the log to a file) or for finer control over the default handlers.
#  
#  If provided this should be a logging configuration dictionary, for more
#  information see:
#  https://docs.python.org/3/library/logging.config.html#logging-config-
#  dictschema
#  
#  This dictionary is merged with the base logging configuration which defines
#  the following:
#  
#  * A logging formatter intended for interactive use called
#    ``console``.
#  * A logging handler that writes to stderr called
#    ``console`` which uses the formatter ``console``.
#  * A logger with the name of this application set to ``DEBUG``
#    level.
#  
#  This example adds a new handler that writes to a file:
#  
#  .. code-block:: python
#  
#     c.Application.logging_config = {
#         'handlers': {
#             'file': {
#                 'class': 'logging.FileHandler',
#                 'level': 'DEBUG',
#                 'filename': '<path/to/file>',
#             }
#         },
#         'loggers': {
#             '<application-name>': {
#                 'level': 'DEBUG',
#                 # NOTE: if you don't list the default "console"
#                 # handler here then it will be disabled
#                 'handlers': ['console', 'file'],
#             },
#         }
#     }
#  Default: {}
# c.Application.logging_config = {}

## Instead of starting the Application, dump configuration to stdout
#  Default: False
# c.Application.show_config = False

## Instead of starting the Application, dump configuration to stdout (as JSON)
#  Default: False
# c.Application.show_config_json = False

#------------------------------------------------------------------------------
# JupyterApp(Application) configuration
#------------------------------------------------------------------------------
## Base class for Jupyter applications

## Answer yes to any prompts.
#  Default: False
# c.JupyterApp.answer_yes = False

## Full path of a config file.
#  Default: ''
# c.JupyterApp.config_file = ''

## Specify a config file to load.
#  Default: ''
# c.JupyterApp.config_file_name = ''

## Generate default config file.
#  Default: False
# c.JupyterApp.generate_config = False

## The date format used by logging formatters for %(asctime)s
#  See also: Application.log_datefmt
# c.JupyterApp.log_datefmt = '%Y-%m-%d %H:%M:%S'

## The Logging format template
#  See also: Application.log_format

# c.JupyterApp.show_config_json = False

#------------------------------------------------------------------------------
# NotebookApp(JupyterApp) configuration
#------------------------------------------------------------------------------
## Set the Access-Control-Allow-Credentials: true header
#  Default: False
# c.NotebookApp.allow_credentials = False

## Set the Access-Control-Allow-Origin header
#  
#          Use '*' to allow any origin to access your server.
#  
#          Takes precedence over allow_origin_pat.
#  Default: ''
# c.NotebookApp.allow_origin = ''

## Use a regular expression for the Access-Control-Allow-Origin header
#  
#          Requests from an origin matching the expression will get replies with:
#  
#              Access-Control-Allow-Origin: origin
#  
#          where `origin` is the origin of the request.
#  
#          Ignored if allow_origin is set.
#  Default: ''
# c.NotebookApp.allow_origin_pat = ''

## Allow password to be changed at login for the notebook server.
#  
#                      While logging in with a token, the notebook server UI will give the opportunity to
#                      the user to enter a new password at the same time that will replace
#                      the token login mechanism.
#  
#                      This can be set to false to prevent changing password from
#  the UI/API.
#  Default: True
# c.NotebookApp.allow_password_change = True

## Allow requests where the Host header doesn't point to a local server
#  
#         By default, requests get a 403 forbidden response if the 'Host' header
#         shows that the browser thinks it's on a non-local domain.
#         Setting this option to True disables this check.
#  
#         This protects against 'DNS rebinding' attacks, where a remote web server
#         serves you a page and then changes its DNS to send later requests to a
#         local IP, bypassing same-origin checks.
#  
#         Local IP addresses (such as 127.0.0.1 and ::1) are allowed as local,
#         along with hostnames configured in local_hostnames.
#  Default: False
# c.NotebookApp.allow_remote_access = False

## Whether to allow the user to run the notebook as root.
#  Default: False
# c.NotebookApp.allow_root = False

## Answer yes to any prompts.
#  See also: JupyterApp.answer_yes
# c.NotebookApp.answer_yes = False

## "
#          Require authentication to access prometheus metrics.
#  Default: True
# c.NotebookApp.authenticate_prometheus = True

## Reload the webapp when changes are made to any Python src files.
#  Default: False
# c.NotebookApp.autoreload = False

## DEPRECATED use base_url
#  Default: '/'
# c.NotebookApp.base_project_url = '/'

## The base URL for the notebook server.
#  
#                                 Leading and trailing slashes can be omitted,
#                                 and will automatically be added.
#  Default: '/'
# c.NotebookApp.base_url = '/'

## Specify what command to use to invoke a web
#                        browser when opening the notebook. If not specified, the
#                        default browser will be determined by the `webbrowser`
#                        standard library module, which allows setting of the
#                        BROWSER environment variable to override it.
#  Default: ''
# c.NotebookApp.browser = ''

## The full path to an SSL/TLS certificate file.
#  Default: ''
# c.NotebookApp.certfile = ''

## The full path to a certificate authority certificate for SSL/TLS client
#  authentication.
#  Default: ''
# c.NotebookApp.client_ca = ''

## Full path of a config file.
#  See also: JupyterApp.config_file
# c.NotebookApp.config_file = ''

## Specify a config file to load.
#  See also: JupyterApp.config_file_name

## The config manager class to use
#  Default: 'notebook.services.config.manager.ConfigManager'
# c.NotebookApp.config_manager_class = 'notebook.services.config.manager.ConfigManager'

## The notebook manager class to use.
#  Default: 'notebook.services.contents.largefilemanager.LargeFileManager'
# c.NotebookApp.contents_manager_class = 'notebook.services.contents.largefilemanager.LargeFileManager'

## Extra keyword arguments to pass to `set_secure_cookie`. See tornado's
#  set_secure_cookie docs for details.
#  Default: {}
# c.NotebookApp.cookie_options = {}

## The random bytes used to secure cookies.
#          By default this is a new random number every time you start the Notebook.
#          Set it to a value in a config file to enable logins to persist across server sessions.
#  
#          Note: Cookie secrets should be kept private, do not share config files with
#          cookie_secret stored in plaintext (you can read the value from a file).
#  Default: b''
# c.NotebookApp.cookie_secret = b''

## The file where the cookie secret is stored.
#  Default: ''
# c.NotebookApp.cookie_secret_file = ''

## Override URL shown to users.
#  
#          Replace actual URL, including protocol, address, port and base URL,
#          with the given value when displaying URL to the users. Do not change
#          the actual connection URL. If authentication token is enabled, the
#          token is added to the custom URL automatically.
#  
#          This option is intended to be used when the URL to display to the user
#          cannot be determined reliably by the Jupyter notebook server (proxified
#          or containerized setups for example).
#  Default: ''
# c.NotebookApp.custom_display_url = ''

## The default URL to redirect to from `/`
#  Default: '/tree'
# c.NotebookApp.default_url = '/tree'

## Disable cross-site-request-forgery protection
#  
#          Jupyter notebook 4.3.1 introduces protection from cross-site request forgeries,
#          requiring API requests to either:
#  
#          - originate from pages served by this server (validated with XSRF cookie and token), or
#          - authenticate with a token
#  
#          Some anonymous compute resources still desire the ability to run code,
#          completely without authentication.
#          These services can disable all authentication and security checks,
#          with the full knowledge of what that implies.
#  Default: False
# c.NotebookApp.disable_check_xsrf = False

## Whether to enable MathJax for typesetting math/TeX
#  
#          MathJax is the javascript library Jupyter uses to render math/LaTeX. It is
#          very large, so you may want to disable it if you have a slow internet
#          connection, or for offline use of the notebook.
#  
#          When disabled, equations etc. will appear as their untransformed TeX
#  source.
#  Default: True
# c.NotebookApp.enable_mathjax = True

## extra paths to look for Javascript notebook extensions
#  Default: []
# c.NotebookApp.extra_nbextensions_path = []

## handlers that should be loaded at higher priority than the default services

#  
#          This allows adding javascript/css to be available from the notebook server machine,
#          or overriding individual files in the IPython
#  Default: []
# c.NotebookApp.extra_static_paths = []

## Extra paths to search for serving jinja templates.
#  
#          Can be used to override templates from notebook.templates.
#  Default: []
# c.NotebookApp.extra_template_paths = []

#  Default: ''
# c.NotebookApp.file_to_run = ''

## Generate default config file.
#  See also: JupyterApp.generate_config
# c.NotebookApp.generate_config = False

## Extra keyword arguments to pass to `get_secure_cookie`. See tornado's

## Deprecated: Use minified JS file or not, mainly use during dev to avoid JS
#  recompilation
#  Default: False
# c.NotebookApp.ignore_minified_js = False

## Supply extra arguments that will be passed to Jinja environment.
#  Default: {}
# c.NotebookApp.jinja_environment_options = {}

## Extra variables to supply to jinja templates when rendering.
#  Default: {}
# c.NotebookApp.jinja_template_vars = {}

## The kernel manager class to use.
#  Default: 'notebook.services.kernels.kernelmanager.MappingKernelManager'
# c.NotebookApp.kernel_manager_class = 'notebook.services.kernels.kernelmanager.MappingKernelManager'

## The kernel spec manager class to use. Should be a subclass of
#  `jupyter_client.kernelspec.KernelSpecManager`.
#  
#  The Api of KernelSpecManager is provisional and might change without warning
#  between this version of Jupyter and the next stable one.
#  Default: 'jupyter_client.kernelspec.KernelSpecManager'
# c.NotebookApp.kernel_spec_manager_class = 'jupyter_client.kernelspec.KernelSpecManager'

## The full path to a private key file for usage with SSL/TLS.
#  Default: ''
# c.NotebookApp.keyfile = ''

## Hostnames to allow as local when allow_remote_access is False.
#  
#         Local IP addresses (such as 127.0.0.1 and ::1) are automatically accepted
#         as local as well.
#  Default: ['localhost']
# c.NotebookApp.local_hostnames = ['localhost']

#  logging]" to install the required dependent packages. Can also be set using
#  the environment variable JUPYTER_ENABLE_JSON_LOGGING=true.
#  Default: False
# c.NotebookApp.log_json = False

## Set the log level by value or name.
#  See also: Application.log_level

#          Should be in the form of a case-sensitive url to MathJax,
#          for example:  /static/components/MathJax/MathJax.js
#  Default: ''
# c.NotebookApp.mathjax_url = ''

## Sets the maximum allowed size of the client request body, specified in the
#  Content-Length request header field. If the size in a request exceeds the
#  configured value, a malformed HTTP message is returned to the client.
#  
#  Note: max_body_size is applied even in streaming mode.
#  Default: 536870912
# c.NotebookApp.max_body_size = 536870912

## Gets or sets the maximum amount of memory, in bytes, that is allocated for use
#  by the buffer manager.
#  Default: 536870912
# c.NotebookApp.max_buffer_size = 536870912

## Gets or sets a lower bound on the open file handles process resource limit.
#  This may need to be increased if you run into an OSError: [Errno 24] Too many
#  open files. This is not applicable when running on Windows.
#  Default: 0
# c.NotebookApp.min_open_files_limit = 0

## Dict of Python modules to load as notebook server extensions. Entry values can

#  will be loaded in alphabetical order.
#  Default: {}
# c.NotebookApp.nbserver_extensions = {}

## The directory to use for notebooks and kernels.
#  Default: ''
# c.NotebookApp.notebook_dir = ''

## Whether to open in a browser after starting.
#                          The specific browser used is platform dependent and
#                          determined by the python standard library `webbrowser`
#                          module, unless it is overridden using the --browser
#                          (NotebookApp.browser) configuration option.
#  Default: True
# c.NotebookApp.open_browser = True

## Hashed password to use for web authentication.
#  
#                        To generate, type in a python/IPython shell:

#                        The string should be of the form type:salt:hashed-
#  password.
#  Default: ''
# c.NotebookApp.password = ''

## Forces users to use a password for the Notebook server.
#                        This is useful in a multi user environment, for instance when
#                        everybody in the LAN can access each other's machine through ssh.
#  
#                        In such a case, serving the notebook server on localhost is not secure
#                        since any user can connect to the notebook server via ssh.
#  Default: False
# c.NotebookApp.password_required = False

## The port the notebook server will listen on (env: JUPYTER_PORT).
#  Default: 8888
# c.NotebookApp.port = 8888

## The number of additional ports to try if the specified port is not available
#  (env: JUPYTER_PORT_RETRIES).

## DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
#  Default: 'disabled'
# c.NotebookApp.pylab = 'disabled'

## If True, display a button in the dashboard to quit
#          (shutdown the notebook server).
#  Default: True
# c.NotebookApp.quit_button = True

## (sec) Time window used to
#          check the message and data rate limits.
#  Default: 3
# c.NotebookApp.rate_limit_window = 3

## Reraise exceptions encountered loading server extensions?
#  Default: False
# c.NotebookApp.reraise_server_extension_failures = False

## DEPRECATED use the nbserver_extensions dict instead
#  Default: []
# c.NotebookApp.server_extensions = []

## The session manager class to use.
#  Default: 'notebook.services.sessions.sessionmanager.SessionManager'
# c.NotebookApp.session_manager_class = 'notebook.services.sessions.sessionmanager.SessionManager'

## Instead of starting the Application, dump configuration to stdout
#  See also: Application.show_config
# c.NotebookApp.show_config = False

## Instead of starting the Application, dump configuration to stdout (as JSON)
#  See also: Application.show_config_json
# c.NotebookApp.show_config_json = False

## Shut down the server after N seconds with no kernels or terminals running and
#  no activity. This can be used together with culling idle kernels
#  (MappingKernelManager.cull_idle_timeout) to shutdown the notebook server when
#  it's not in use. This is not precisely timed: it may shut down up to a minute
#  later. 0 (the default) disables this automatic shutdown.
#  Default: 0
# c.NotebookApp.shutdown_no_activity_timeout = 0

## The UNIX socket the notebook server will listen on.
#  Default: ''
# c.NotebookApp.sock = ''

## The permissions mode for UNIX socket creation (default: 0600).
#  Default: '0600'
# c.NotebookApp.sock_mode = '0600'

## Supply SSL options for the tornado HTTPServer.
#              See the tornado docs for details.
#  Default: {}
# c.NotebookApp.ssl_options = {}

## Supply overrides for terminado. Currently only supports "shell_command". On
#  Unix, if "shell_command" is not provided, a non-login shell is launched by
#  default when the notebook server is connected to a terminal, a login shell
#  otherwise.
#  Default: {}
# c.NotebookApp.terminado_settings = {}

## Set to False to disable terminals.
#  
#           This does *not* make the notebook server more secure by itself.
#           Anything the user can in a terminal, they can also do in a notebook.
#  
#           Terminals may also be automatically disabled if the terminado package
#           is not available.
#  Default: True
# c.NotebookApp.terminals_enabled = True

## Token used for authenticating first-time connections to the server.
#  
#          The token can be read from the file referenced by JUPYTER_TOKEN_FILE or set directly
#          with the JUPYTER_TOKEN environment variable.
#  
#          When no password is enabled,
#          the default is to generate a new, random token.
#  
#          Setting to an empty string disables authentication altogether, which
#  is NOT RECOMMENDED.
#  Default: '<generated>'
# c.NotebookApp.token = '<generated>'

## Supply overrides for the tornado.web.Application that the Jupyter notebook
#  uses.
#  Default: {}
# c.NotebookApp.tornado_settings = {}

## Whether to trust or not X-Scheme/X-Forwarded-Proto and X-Real-Ip/X-Forwarded-
#  For headers sent by the upstream reverse proxy. Necessary if the proxy handles
#  SSL
#  Default: False
# c.NotebookApp.trust_xheaders = False

## Disable launching browser by redirect file
#  
#          For versions of notebook > 5.7.2, a security feature measure was added that
#          prevented the authentication token used to launch the browser from being visible.
#          This feature makes it difficult for other users on a multi-user system from
#          running code in your Jupyter session as you.
#  
#          However, some environments (like Windows Subsystem for Linux (WSL) and Chromebooks),
#          launching a browser using a redirect file can lead the browser failing to load.
#          This is because of the difference in file structures/paths between the runtime and
#          the browser.
#  
#          Disabling this setting to False will disable this behavior, allowing the browser
#          to launch by using a URL and visible token (as before).
#  Default: True
# c.NotebookApp.use_redirect_file = True

## DEPRECATED, use tornado_settings
#  Default: {}
# c.NotebookApp.webapp_settings = {}

## Specify Where to open the notebook on startup. This is the
#          `new` argument passed to the standard library method `webbrowser.open`.
#          The behaviour is not guaranteed, but depends on browser support. Valid
#          values are:
#  
#           - 2 opens a new tab,
#           - 1 opens a new window,
#           - 0 opens in an existing window.
#  
#          See the `webbrowser.open` documentation for details.
#  Default: 2
# c.NotebookApp.webbrowser_open_new = 2

## Set the tornado compression options for websocket connections.
#  
#  This value will be returned from
#  :meth:`WebSocketHandler.get_compression_options`. None (default) will disable
#  compression. A dict (even an empty one) will enable compression.
#  
#  See the tornado docs for WebSocketHandler.get_compression_options for details.
#  Default: None
# c.NotebookApp.websocket_compression_options = None

## The base URL for websockets,
#          if it differs from the HTTP server (hint: it almost certainly doesn't).
#  
#          Should be in the form of an HTTP origin: ws[s]://hostname[:port]
#  Default: ''
# c.NotebookApp.websocket_url = ''

## Time to wait for a kernel to terminate before killing it, in seconds. When a
#  shutdown request is initiated, the kernel will be immediately sent an
#  interrupt (SIGINT), followedby a shutdown_request message, after 1/2 of
#  `shutdown_wait_time`it will be sent a terminate (SIGTERM) request, and finally

# Session(Configurable) configuration
#------------------------------------------------------------------------------
## Object for handling serialization and sending of messages.
#  
#      The Session object handles building messages and sending them
#      with ZMQ sockets or ZMQStream objects.  Objects can communicate with each
#      other over the network via Session objects, and only need to work with the
#      dict-based IPython message spec. The Session will handle
#      serialization/deserialization, security, and metadata.
#  
#      Sessions support configurable serialization via packer/unpacker traits,
#      and signing with HMAC digests via the key/keyfile traits.
#  
#      Parameters
#      ----------
#  
#      debug : bool
#          whether to trigger extra debugging statements
#      packer/unpacker : str : 'json', 'pickle' or import_string
#          importstrings for methods to serialize message parts.  If just
#          'json' or 'pickle', predefined JSON and pickle packers will be used.
#          Otherwise, the entire importstring must be used.
#  
#          The functions must accept at least valid JSON input, and output
#  *bytes*.
#  
#          For example, to use msgpack:
#          packer = 'msgpack.packb', unpacker='msgpack.unpackb'
#      pack/unpack : callables
#          You can also set the pack/unpack callables for serialization directly.
#      session : bytes
#          the ID of this Session object.  The default is to generate a new UUID.
#      username : unicode
#          username added to message headers.  The default is to ask the OS.
#      key : bytes
#          The key used to initialize an HMAC signature.  If unset, messages
#          will not be signed or checked.
#      keyfile : filepath
#          The file containing a key.  If this is set, `key` will be initialized
#          to the contents of the file.

## Threshold (in bytes) beyond which an object's buffer should be extracted to
#  avoid pickling.
#  Default: 1024
# c.Session.buffer_threshold = 1024

## Whether to check PID to protect against calls after fork.
#

# c.Session.check_pid = True

## Threshold (in bytes) beyond which a buffer should be sent without copying.
#  Default: 65536
# c.Session.copy_threshold = 65536

## Debug output in the Session

#  Default: 65536
# c.Session.digest_history_size = 65536

## The maximum number of items for a container to be introspected for custom serialization.
#          Containers larger than this are pickled outright.
#  Default: 64
# c.Session.item_threshold = 64

## execution key, for signing messages.
#  Default: b''
# c.Session.key = b''

## path to file containing execution key.
#  Default: ''
# c.Session.keyfile = ''

## Metadata dictionary, which serves as the default top-level metadata dict for
#  each message.
#  Default: {}
# c.Session.metadata = {}

## The name of the packer for serializing messages.
#              Should be one of 'json', 'pickle', or an import name
#              for a custom callable serializer.
#  Default: 'json'
# c.Session.packer = 'json'

## The UUID identifying this session.
#  Default: ''
# c.Session.session = ''

## The digest scheme used to construct the message signatures.
#          Must have the form 'hmac-HASH'.
#  Default: 'hmac-sha256'
# c.Session.signature_scheme = 'hmac-sha256'

## The name of the unpacker for unserializing messages.

#  Default: []
# c.MappingKernelManager.allowed_message_types = []

## Whether messages from kernels whose frontends have disconnected should be buffered in-memory.
#          When True (default), messages are buffered and replayed on reconnect,
#          avoiding lost messages due to interrupted connectivity.
#          Disable if long-running kernels will produce too much output while
#          no frontends are connected.

#  Default: False
# c.MappingKernelManager.cull_connected = False

## Timeout (in seconds) after which a kernel is considered idle and ready to be culled.
#          Values of 0 or lower disable culling. Very short timeouts may result in kernels being culled
#          for users with poor network connections.
#  Default: 0
# c.MappingKernelManager.cull_idle_timeout = 0

## The interval (in seconds) on which to check for idle kernels exceeding the
#  cull timeout value.
#  Default: 300
# c.MappingKernelManager.cull_interval = 300

## The name of the default kernel to start
#  See also: MultiKernelManager.default_kernel_name
# c.MappingKernelManager.default_kernel_name = 'python3'

## Timeout for giving up on a kernel (in seconds).
#          On starting and restarting kernels, we check whether the
#          kernel is running and responsive by sending kernel_info_requests.
#          This sets the timeout in seconds for how long the kernel can take
#          before being presumed dead.
#          This affects the MappingKernelManager (which handles kernel restarts)
#          and the ZMQChannelsHandler (which handles the startup).
#  Default: 60
# c.MappingKernelManager.kernel_info_timeout = 60

## The kernel manager class.  This is configurable to allow

# ContentsManager(LoggingConfigurable) configuration
#------------------------------------------------------------------------------
## Base class for serving files and directories.
#  
#      This serves any text or binary file,
#      as well as directories,
#      with special handling for JSON notebook documents.
#  
#      Most APIs take a path argument,
#      which is always an API-style unicode path,
#      and always refers to a directory.
#  
#      - unicode, not url-escaped
#      - '/'-separated
#      - leading and trailing '/' will be stripped

# c.ContentsManager.checkpoints_kwargs = {}

## handler class to use when serving raw file requests.
#  
#          Default is a fallback that talks to the ContentsManager API,
#          which may be inefficient, especially for large files.
#  
#          Local files-based ContentsManagers can use a StaticFileHandler subclass,
#          which will be much more efficient.
#  
#          Access to these files should be Authenticated.
#  Default: 'notebook.files.handlers.FilesHandler'
# c.ContentsManager.files_handler_class = 'notebook.files.handlers.FilesHandler'

## Extra parameters to pass to files_handler_class.
#  
#          For example, StaticFileHandlers generally expect a `path` argument

#  
#          - model: the model to be saved. Includes file contents.
#            Modifying this dict will affect the file that is stored.

#  
#  root_dir : unicode
#      A directory against which API-style paths are to be resolved.
#  
#  log : logging.Logger

## By default notebooks are saved on disk on a temporary file and then if successfully written, it replaces the old ones.
#        This procedure, namely 'atomic_writing', causes some bugs on file system without operation order enforcement (like some networked fs).
#        If set to False, the new notebook is written directly on the old one which could fail (eg: full filesystem or quota )

# c.NotebookApp.custom_display_url = ''

## The default URL to redirect to from `/`
#  Default: '/tree'
# c.NotebookApp.default_url = '/tree'

## Disable cross-site-request-forgery protection
#  
#          Jupyter notebook 4.3.1 introduces protection from cross-site request forgeries,
#          requiring API requests to either:
#  
#          - originate from pages served by this server (validated with XSRF cookie and token), or
#          - authenticate with a token
#  
#          Some anonymous compute resources still desire the ability to run code,
#          completely without authentication.
#          These services can disable all authentication and security checks,
#          with the full knowledge of what that implies.
#  Default: False
# c.NotebookApp.disable_check_xsrf = False

## Whether to enable MathJax for typesetting math/TeX
#  
#          MathJax is the javascript library Jupyter uses to render math/LaTeX. It is

#  Default: ''
# c.NotebookApp.mathjax_url = ''

## Sets the maximum allowed size of the client request body, specified in the

#  open files. This is not applicable when running on Windows.
#  Default: 0
# c.NotebookApp.min_open_files_limit = 0

## Dict of Python modules to load as notebook server extensions. Entry values can
#  be used to enable and disable the loading of the extensions. The extensions
#  will be loaded in alphabetical order.

## The directory to use for notebooks and kernels.
#  Default: ''
c.NotebookApp.notebook_dir = '/home/luyanfeng/my_code/my_github/susu-pytorch-tutorials-notes'

## Whether to open in a browser after starting.
#                          The specific browser used is platform dependent and
#                          determined by the python standard library `webbrowser`
#                          module, unless it is overridden using the --browser
#                          (NotebookApp.browser) configuration option.
#  Default: True
# c.NotebookApp.open_browser = True

## Hashed password to use for web authentication.
#  
#                        To generate, type in a python/IPython shell:

#                        The string should be of the form type:salt:hashed-
#  password.
#  Default: ''
# c.NotebookApp.password = ''

## Forces users to use a password for the Notebook server.
#                        This is useful in a multi user environment, for instance when
#                        everybody in the LAN can access each other's machine through ssh.
#  
#                        In such a case, serving the notebook server on localhost is not secure
#                        since any user can connect to the notebook server via ssh.
#  Default: False
# c.NotebookApp.password_required = False

## The port the notebook server will listen on (env: JUPYTER_PORT).
#  Default: 8888
# c.NotebookApp.port = 8888

## The number of additional ports to try if the specified port is not available
#  (env: JUPYTER_PORT_RETRIES).
#  Default: 50
# c.NotebookApp.port_retries = 50

## DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
#  Default: 'disabled'

#          (shutdown the notebook server).
#  Default: True
# c.NotebookApp.quit_button = True

## (sec) Time window used to
#          check the message and data rate limits.
#  Default: 3
# c.NotebookApp.rate_limit_window = 3

## Reraise exceptions encountered loading server extensions?
#  Default: False
# c.NotebookApp.reraise_server_extension_failures = False

## DEPRECATED use the nbserver_extensions dict instead
#  Default: []
# c.NotebookApp.server_extensions = []

## The session manager class to use.
#  Default: 'notebook.services.sessions.sessionmanager.SessionManager'
# c.NotebookApp.session_manager_class = 'notebook.services.sessions.sessionmanager.SessionManager'

## Instead of starting the Application, dump configuration to stdout
#  See also: Application.show_config
# c.NotebookApp.show_config = False

## Instead of starting the Application, dump configuration to stdout (as JSON)
#  See also: Application.show_config_json
# c.NotebookApp.show_config_json = False

## Shut down the server after N seconds with no kernels or terminals running and
#  no activity. This can be used together with culling idle kernels
#  (MappingKernelManager.cull_idle_timeout) to shutdown the notebook server when
#  it's not in use. This is not precisely timed: it may shut down up to a minute
#  later. 0 (the default) disables this automatic shutdown.
#  Default: 0
# c.NotebookApp.shutdown_no_activity_timeout = 0

## The UNIX socket the notebook server will listen on.
#  Default: ''
# c.NotebookApp.sock = ''

## The permissions mode for UNIX socket creation (default: 0600).
#  Default: '0600'
# c.NotebookApp.sock_mode = '0600'

## Supply SSL options for the tornado HTTPServer.
#              See the tornado docs for details.
#  Default: {}
# c.NotebookApp.ssl_options = {}

## Supply overrides for terminado. Currently only supports "shell_command". On
#  Unix, if "shell_command" is not provided, a non-login shell is launched by
#  default when the notebook server is connected to a terminal, a login shell
#  otherwise.
#  Default: {}
# c.NotebookApp.terminado_settings = {}

## Set to False to disable terminals.
#  
#           This does *not* make the notebook server more secure by itself.
#           Anything the user can in a terminal, they can also do in a notebook.
#  
#           Terminals may also be automatically disabled if the terminado package
#           is not available.
#  Default: True
# c.NotebookApp.terminals_enabled = True

## Token used for authenticating first-time connections to the server.
#  
#          The token can be read from the file referenced by JUPYTER_TOKEN_FILE or set directly
#          with the JUPYTER_TOKEN environment variable.
#  
#          When no password is enabled,
#          the default is to generate a new, random token.
#  
#          Setting to an empty string disables authentication altogether, which
#  is NOT RECOMMENDED.
#  Default: '<generated>'
# c.NotebookApp.token = '<generated>'

## Supply overrides for the tornado.web.Application that the Jupyter notebook
#  uses.
#  Default: {}
# c.NotebookApp.tornado_settings = {}

## Whether to trust or not X-Scheme/X-Forwarded-Proto and X-Real-Ip/X-Forwarded-
#  For headers sent by the upstream reverse proxy. Necessary if the proxy handles
#  SSL
#  Default: False
# c.NotebookApp.trust_xheaders = False

## Disable launching browser by redirect file
#  
#          For versions of notebook > 5.7.2, a security feature measure was added that
#          prevented the authentication token used to launch the browser from being visible.
#          This feature makes it difficult for other users on a multi-user system from
#          running code in your Jupyter session as you.
#  
#          However, some environments (like Windows Subsystem for Linux (WSL) and Chromebooks),
#          launching a browser using a redirect file can lead the browser failing to load.
#          This is because of the difference in file structures/paths between the runtime and
#          the browser.
#  
#          Disabling this setting to False will disable this behavior, allowing the browser
#          to launch by using a URL and visible token (as before).
#  Default: True
# c.NotebookApp.use_redirect_file = True

## DEPRECATED, use tornado_settings
#  Default: {}
# c.NotebookApp.webapp_settings = {}

## Specify Where to open the notebook on startup. This is the
#          `new` argument passed to the standard library method `webbrowser.open`.
#          The behaviour is not guaranteed, but depends on browser support. Valid
#          values are:
#  
#           - 2 opens a new tab,
#           - 1 opens a new window,
#           - 0 opens in an existing window.
#  
#          See the `webbrowser.open` documentation for details.
#  Default: 2
# c.NotebookApp.webbrowser_open_new = 2

## Set the tornado compression options for websocket connections.
#  
#  This value will be returned from
#  :meth:`WebSocketHandler.get_compression_options`. None (default) will disable
#  compression. A dict (even an empty one) will enable compression.
#  
#  See the tornado docs for WebSocketHandler.get_compression_options for details.
#  Default: None
# c.NotebookApp.websocket_compression_options = None

## The base URL for websockets,
#          if it differs from the HTTP server (hint: it almost certainly doesn't).
#  
#          Should be in the form of an HTTP origin: ws[s]://hostname[:port]
#  Default: ''
# c.NotebookApp.websocket_url = ''

# c.KernelManager.shell_port = 0

## Time to wait for a kernel to terminate before killing it, in seconds. When a
#  shutdown request is initiated, the kernel will be immediately sent an
#  interrupt (SIGINT), followedby a shutdown_request message, after 1/2 of
#  `shutdown_wait_time`it will be sent a terminate (SIGTERM) request, and finally

# Session(Configurable) configuration
#------------------------------------------------------------------------------
## Object for handling serialization and sending of messages.
#  
#      The Session object handles building messages and sending them
#      with ZMQ sockets or ZMQStream objects.  Objects can communicate with each
#      other over the network via Session objects, and only need to work with the
#      dict-based IPython message spec. The Session will handle
#      serialization/deserialization, security, and metadata.
#  
#      Sessions support configurable serialization via packer/unpacker traits,
#      and signing with HMAC digests via the key/keyfile traits.
#  
#      Parameters
#      ----------
#  
#      debug : bool
#          whether to trigger extra debugging statements
#      packer/unpacker : str : 'json', 'pickle' or import_string
#          importstrings for methods to serialize message parts.  If just
#          'json' or 'pickle', predefined JSON and pickle packers will be used.
#          Otherwise, the entire importstring must be used.
#  
#          The functions must accept at least valid JSON input, and output
#  *bytes*.
#  
#          For example, to use msgpack:
#          packer = 'msgpack.packb', unpacker='msgpack.unpackb'
#      pack/unpack : callables
#          You can also set the pack/unpack callables for serialization directly.
#      session : bytes
#          the ID of this Session object.  The default is to generate a new UUID.
#      username : unicode
#          username added to message headers.  The default is to ask the OS.
#      key : bytes
#          The key used to initialize an HMAC signature.  If unset, messages
#          will not be signed or checked.
#      keyfile : filepath
#          The file containing a key.  If this is set, `key` will be initialized
#          to the contents of the file.

    authentication.
    Default: ''
    Equivalent to: [--NotebookApp.client_ca]
--notebook-dir=<Unicode>
    The directory to use for notebooks and kernels.
    Default: ''
    Equivalent to: [--NotebookApp.notebook_dir]
--browser=<Unicode>
    Specify what command to use to invoke a web
                          browser when opening the notebook. If not specified, the
                          default browser will be determined by the `webbrowser`
                          standard library module, which allows setting of the
                          BROWSER environment variable to override it.
    Default: ''
    Equivalent to: [--NotebookApp.browser]
--pylab=<Unicode>
    DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
    Default: 'disabled'
    Equivalent to: [--NotebookApp.pylab]
--gateway-url=<Unicode>
    The url of the Kernel or Enterprise Gateway server where
            kernel specifications are defined and kernel management takes place.
            If defined, this Notebook server acts as a proxy for all kernel
            management and kernel specification retrieval.  (JUPYTER_GATEWAY_URL env var)
    Default: None
    Equivalent to: [--GatewayClient.url]

Examples
--------

    jupyter notebook                       # start the notebook
    jupyter notebook --certfile=mycert.pem # use SSL/TLS certificate
    jupyter notebook password              # enter a password to protect the server
