IPython notebook optionsΒΆ

Any of the IPython kernel options can also be used.

NotebookNotary.algorithm : ‘md5’|’sha1’|’sha224’|’sha256’|’sha384’|’sha512’

Default: ‘sha256’

The hashing algorithm used to sign notebooks.

NotebookNotary.secret : Bytes

Default: ‘’

The secret key with which notebooks are signed.

NotebookNotary.secret_file : Unicode

Default: u’‘

The file where the secret key is stored.

MappingKernelManager.kernel_manager_class : DottedObjectName

Default: ‘IPython.kernel.ioloop.IOLoopKernelManager’

The kernel manager class. This is configurable to allow subclassing of the KernelManager for customized behavior.

MappingKernelManager.root_dir : Unicode

Default: u’/private/tmp/ipython/docs’

No description

NotebookApp.base_project_url : Unicode

Default: ‘/’

DEPRECATED use base_url

NotebookApp.base_url : Unicode

Default: ‘/’

The base URL for the notebook server.

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

NotebookApp.browser : Unicode

Default: u’‘

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 : Unicode

Default: u’‘

The full path to an SSL/TLS certificate file.

NotebookApp.cookie_secret : Bytes

Default: ‘’

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.copy_config_files : Bool

Default: False

Whether to install the default config files into the profile dir. If a new profile is being created, and IPython contains config files for that profile, then they will be staged into the new directory. Otherwise, default config files will be automatically generated.

NotebookApp.enable_mathjax : Bool

Default: True

Whether to enable MathJax for typesetting math/TeX

MathJax is the javascript library IPython 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.

NotebookApp.extra_config_file : Unicode

Default: u’‘

Path to an extra config file to load.

If specified, load this config file in addition to any other IPython config.

NotebookApp.extra_static_paths : List

Default: []

Extra paths to search for serving static files.

This allows adding javascript/css to be available from the notebook server machine, or overriding individual files in the IPython

NotebookApp.file_to_run : Unicode

Default: ‘’

No description

NotebookApp.ip : Unicode

Default: ‘localhost’

The IP address the notebook server will listen on.

NotebookApp.ipython_dir : Unicode

Default: u’‘

The name of the IPython directory. This directory is used for logging configuration (through profiles), history storage, etc. The default is usually $HOME/.ipython. This options can also be specified through the environment variable IPYTHONDIR.

NotebookApp.jinja_environment_options : Dict

Default: {}

Supply extra arguments that will be passed to Jinja environment.

NotebookApp.keyfile : Unicode

Default: u’‘

The full path to a private key file for usage with SSL/TLS.

NotebookApp.log_datefmt : Unicode

Default: ‘%Y-%m-%d %H:%M:%S’

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

NotebookApp.log_format : Unicode

Default: ‘[%(name)s]%(highlevel)s %(message)s’

The Logging format template

NotebookApp.log_level : 0|10|20|30|40|50|’DEBUG’|’INFO’|’WARN’|’ERROR’|’CRITICAL’

Default: 30

Set the log level by value or name.

NotebookApp.mathjax_url : Unicode

Default: ‘’

The url for MathJax.js.

NotebookApp.nbextensions_path : List

Default: []

paths for Javascript extensions. By default, this is just IPYTHONDIR/nbextensions

NotebookApp.notebook_dir : Unicode

Default: u’/private/tmp/ipython/docs’

The directory to use for notebooks and kernels.

NotebookApp.notebook_manager_class : DottedObjectName

Default: ‘IPython.html.services.notebooks.filenbmanager.FileNotebookMa...

The notebook manager class to use.

NotebookApp.open_browser : Bool

Default: True

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.

NotebookApp.overwrite : Bool

Default: False

Whether to overwrite existing config files when copying

NotebookApp.password : Unicode

Default: u’‘

Hashed password to use for web authentication.

To generate, type in a python/IPython shell:

from IPython.lib import passwd; passwd()

The string should be of the form type:salt:hashed-password.

NotebookApp.port : Integer

Default: 8888

The port the notebook server will listen on.

NotebookApp.port_retries : Integer

Default: 50

The number of additional ports to try if the specified port is not available.

NotebookApp.profile : Unicode

Default: u’default’

The IPython profile to use.

NotebookApp.trust_xheaders : Bool

Default: False

Whether to trust or not X-Scheme/X-Forwarded-Proto and X-Real-Ip/X -Forwarded-For headerssent by the upstream reverse proxy. Necessary if the proxy handles SSL

NotebookApp.verbose_crash : Bool

Default: False

Create a massive crash report when IPython encounters what may be an internal error. The default is to append a short message to the usual traceback

NotebookApp.webapp_settings : Dict

Default: {}

Supply overrides for the tornado.web.Application that the IPython notebook uses.

KernelManager.autorestart : Bool

Default: False

Should we autorestart the kernel if it dies.

KernelManager.ip : Unicode

Default: u’‘

Set the kernel’s IP address [default localhost]. If the IP address is something other than localhost, then Consoles on other machines will be able to connect to the Kernel, so be careful!

KernelManager.kernel_cmd : List

Default: []

The Popen Command to launch the kernel. Override this if you have a custom kernel. If kernel_cmd is specified in a configuration file, IPython 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 IPython command line.

KernelManager.transport : ‘tcp’|’ipc’

Default: ‘tcp’

No description

FileNotebookManager.checkpoint_dir : Unicode

Default: ‘.ipynb_checkpoints’

The directory name in which to keep notebook checkpoints

This is a path relative to the notebook’s own directory.

By default, it is .ipynb_checkpoints

FileNotebookManager.hide_globs : List

Default: [u’__pycache__’]

Glob patterns to hide in file and directory listings.

FileNotebookManager.notebook_dir : Unicode

Default: u’/private/tmp/ipython/docs’

No description

FileNotebookManager.save_script : Bool

Default: False

Automatically create a Python script when saving the notebook.

For easier use of import, %run and %load across notebooks, a <notebook- name>.py script will be created next to any <notebook-name>.ipynb on each save. This can also be set with the short –script flag.

NotebookManager.hide_globs : List

Default: [u’__pycache__’]

Glob patterns to hide in file and directory listings.

InlineBackend.close_figures : Bool

Default: True

Close all figures at the end of each cell.

When True, ensures that each cell starts with no active figures, but it also means that one must keep track of references in order to edit or redraw figures in subsequent cells. This mode is ideal for the notebook, where residual plots from other cells might be surprising.

When False, one must call figure() to create new figures. This means that gcf() and getfigs() can reference figures created in other cells, and the active figure can continue to be edited with pylab/pyplot methods that reference the current active figure. This mode facilitates iterative editing of figures, and behaves most consistently with other matplotlib backends, but figure barriers between cells must be explicit.

InlineBackend.figure_format : Unicode

Default: u’‘

The figure format to enable (deprecated use figure_formats instead)

InlineBackend.figure_formats : Set

Default: set([‘png’])

A set of figure formats to enable: ‘png’, ‘retina’, ‘jpeg’, ‘svg’, ‘pdf’.

InlineBackend.print_figure_kwargs : Dict

Default: {‘bbox_inches’: ‘tight’}

Extra kwargs to be passed to fig.canvas.print_figure.

Logical examples include: bbox_inches, quality (for jpeg figures), etc.

InlineBackend.rc : Dict

Default: {‘font.size’: 10, ‘figure.figsize’: (6.0, 4.0), ‘figure.facec...

Subset of matplotlib rcParams that should be different for the inline backend.
