The notebook server can be run with a variety of command line arguments. A list of available options can be found below in the options section.
Defaults for these options can also be set by creating a file named
jupyter_notebook_config.py
in your Jupyter folder. The Jupyter
folder is in your home directory, ~/.jupyter
.
To create a jupyter_notebook_config.py
file, with all the defaults
commented out, you can use the following command line:
$ jupyter notebook --generate-config
This list of options can be generated by running the following and hitting enter:
$ jupyter notebook --help

The file where the cookie secret is stored.
Default: '/tree'
The default URL to redirect to from /
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.

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.
