jupyter notebook –help-all
The Jupyter HTML Notebook.

This launches a Tornado based HTML Notebook Server that serves up an
HTML5/Javascript Notebook client.

Subcommands

Subcommands are launched as jupyter-notebook cmd [args]. For information onusing subcommand ‘cmd’, do: jupyter-notebook cmd -h.

list
List currently running notebook servers.
stop
Stop currently running notebook server for a given port
password
Set a password for the notebook server.

–pylab= (NotebookApp.pylab)
Default: ‘disabled’
DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.

Class parameters

Parameters are set from command-line arguments of the form:
--Class.trait=value. This line is evaluated in Python, so simple expressions
are allowed, e.g.:: --C.a='range(3)' For setting C.a=[0,1,2].

NotebookApp options

–NotebookApp.allow_credentials=
Default: False
Set the Access-Control-Allow-Credentials: true header
–NotebookApp.allow_origin=
Default: ”
Set the Access-Control-Allow-Origin header
Use ‘*’ to allow any origin to access your server.
Takes precedence over allow_origin_pat.
–NotebookApp.allow_origin_pat=
Default: ”
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.
–NotebookApp.allow_password_change=
Default: True
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.
–NotebookApp.allow_remote_access=
Default: False
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.
–NotebookApp.allow_root=
Default: False
Whether to allow the user to run the notebook as root.
–NotebookApp.answer_yes=
Default: False
Answer yes to any prompts.
–NotebookApp.base_project_url=
Default: ‘/’
DEPRECATED use base_url

The base URL for the notebook server.
Leading and trailing slashes can be omitted, and will automatically be
added.
–NotebookApp.browser=
Default: ”
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.
–NotebookApp.certfile=
Default: ”
The full path to an SSL/TLS certificate file.
–NotebookApp.client_ca=
Default: ”
The full path to a certificate authority certificate for SSL/TLS client
authentication.

Default: ”
Full path of a config file.
–NotebookApp.config_file_name=
Default: ”
Specify a config file to load.

Default: {}
Extra keyword arguments to pass to set_secure_cookie. See tornado’s
set_secure_cookie docs for details.
–NotebookApp.cookie_secret=
Default: b”
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).
–NotebookApp.cookie_secret_file=
Default: ”
The file where the cookie secret is stored.
–NotebookApp.custom_display_url=
Default: ”
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).
–NotebookApp.default_url=
Default: ‘/tree’
The default URL to redirect to from /
–NotebookApp.disable_check_xsrf=
Default: False
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.
–NotebookApp.enable_mathjax=
Default: True
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.

Forces users to use a password for the Notebook server. This is useful in a

–NotebookApp.shutdown_no_activity_timeout=
Default: 0
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.
–NotebookApp.ssl_options=
Default: {}

details.
–NotebookApp.terminado_settings=
Default: {}
Supply overrides for terminado. Currently only supports “shell_command”.
–NotebookApp.terminals_enabled=
Default: True
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.
–NotebookApp.token=
Default: ”
Token used for authenticating first-time connections to the server.

– 0 opens in an existing window.
See the webbrowser.open documentation for details.
–NotebookApp.websocket_compression_options=
Default: None
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.

something other than localhost, then Consoles on other machines will be able
to connect to the Kernel, so be careful!
–KernelManager.kernel_cmd=
Default: []
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
pass any arguments to the kernel, because it cannot make any assumptions
about the arguments that the kernel understands. In particular, this means
that the kernel does not receive the option –debug if it given on the
Jupyter command line.
–KernelManager.shell_port=
Default: 0
set the shell (ROUTER) port [default: random]
–KernelManager.shutdown_wait_time=
Default: 5.0

effective if cull_idle_timeout > 0.
–MappingKernelManager.cull_idle_timeout=
Default: 0
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: 300
The interval (in seconds) on which to check for idle kernels exceeding the
cull timeout value.
–MappingKernelManager.default_kernel_name=

–MappingKernelManager.kernel_info_timeout=
Default: 60
Timeout for giving up on a kernel (in seconds).
On starting and restarting kernels, we check whether the kernel is running

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: ‘notebook.files.handlers.FilesHandler’
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.

which will be much more efficient.
Access to these files should be Authenticated.
–FileContentsManager.files_handler_params=
