jupyter_notebook_config.py的配置详解

# Configuration file for jupyter-notebook.

## This is an application.

## The date format used by logging formatters for %(asctime)s

## Set the Access-Control-Allow-Credentials: true header
#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.
#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.
#c.NotebookApp.allow_origin_pat = ''

## Allow password to be changed at login for the notebook server.
#  
#  While loggin 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.
#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.

#  Leading and trailing slashes can be omitted, and will automatically be added.
#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.

#c.NotebookApp.cookie_options = {}

#  number every time you start the Notebook. Set it to a value in a config file
#  to enable logins to persist across server sessions.

## 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.

#  containerized setups for example).

## The default URL to redirect to from `/`
#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.
#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

#  MathJax, for example:  /static/components/MathJax/MathJax.js
#c.NotebookApp.mathjax_url = ''

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

## 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

#c.NotebookApp.shutdown_no_activity_timeout = 0

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

## Supply overrides for terminado. Currently only supports "shell_command".
#c.NotebookApp.terminado_settings = {}

## Set to False to disable terminals.
#  
#  This does *not* make the notebook server more secure by itself. Anything the

#  
#  Terminals may also be automatically disabled if the terminado package is not
#  available.
#c.NotebookApp.terminals_enabled = True

## Token used for authenticating first-time connections to the server.

#  See the `webbrowser.open` documentation for details.
#c.NotebookApp.webbrowser_open_new = 2

## Set the tornado compression options for websocket connections.

## DEPRECATED: Use kernel_name instead.
#  
#  The Popen Command to launch the kernel. Override this if you have a custom
#  kernel. If kernel_cmd is specified in a configuration file, Jupyter does not

# 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.
#c.Session.buffer_threshold = 1024

## The digest scheme used to construct the message signatures. Must have the form
