nbexec

nbexec is a dead-simple tool for executing Jupyter notebooks from the command line. It can run single notebooks, multiple notebooks, and/or an entire directory of notebooks in one short command.

nbexec runs your notebook using Jupyter's (browserless) nbconvert execution API. Then, if the notebook ran without errors, nbexec resaves the notebook in place.

Note: nbexec is in the early stages of development. Features may change/break in the future. Pinning your package installation to the current version is advised.

Installation

pip install nbexec

Basic usage

To run one notebook:

nbexec path/to/my/notebook.ipynb

To run multiple notebooks:

nbexec nb-one.ipynb foo/nb-two.ipynb

To run all notebooks in the first level of a directory:

nbexec path/to/directory-of-notebooks

To run all notebooks in the first three levels of a directory:

nbexec --max-depth 3 path/to/directory-of-notebooks

Command-line options

usage: nbexec [-h] [--max-depth MAX_DEPTH] [--timeout TIMEOUT]
              [--allow-iopub-timeout] [--record-timing]
              [--kernel-name KERNEL_NAME] [--quiet] [--stdout]
              notebooks [notebooks ...]

Execute Jupyter notebooks on the command line.

positional arguments:
  notebooks             One or more notebooks, or directories containing
                        notebooks.

optional arguments:
  -h, --help            show this help message and exit
  --max-depth MAX_DEPTH
                        The number of directory levels to scan for notebooks.
                        (default: 1)
  --timeout TIMEOUT     How long to wait, in seconds, for any given notebook
                        cell to before raising an exception. (default: None)
  --allow-iopub-timeout
                        Don't raise an error on IOPub timeouts. (default:
                        False)
  --record-timing       Store the execution timings in each cell's metadata.
                        (default: False)
  --kernel-name KERNEL_NAME
                        The name of the kernel to use, e.g., 'python3'. If
                        None, nbexec uses the kernel specified in the
                        notebook. (default: None)
  --quiet               Don't print notifications, other than errors.
                        (default: False)
  --stdout              Instead of saving the notebook in place, pipe the
                        executed notebook to stdout. This option is not
                        available if you are executing multiple notebooks at
                        once. (default: False)

Note: nbexec uses Jupyter's nbconvert module. See
https://nbconvert.readthedocs.io/en/latest/execute_api.html for context.

Changelog

v0.2.0

• By default, do not record cell execution timings. (Use --record-timing to record them.)

v0.1.0

• By default, raise errors on IOPub timeouts. (Use --allow-iopub-timeout to prevent raising those errors.)

Possible future features / improvements
