jupyterlab-kernelspy
A Jupyter Lab extension for inspecting messages to/from a kernel.
Requirements
Install
pip install jupyterlab-kernelspy
Update
From JupyterLab 3.0 onwards, extensions are distributed as Python packages. Use the same Python
package manager you used to install the extension to update it.
For JupyterLab 0.34 - 2.2.x, you can update the extension to the latest compatible version with:
jupyter labextension update jupyterlab-kernelspy
Usage
Once the extension is installed, it should add a button to your notebook toolbar (a yellow {:}
icon).
Click this button to open a log view for that notebook.
Contributing
Development install
Note: You will need NodeJS to build the extension package.
The jlpm
command is JupyterLab's pinned version of
yarn that is installed with JupyterLab. You may use
yarn
or npm
in lieu of jlpm
below.
pip install -e .
jupyter labextension develop . --overwrite
jlpm run build
You can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension's source and automatically rebuild the extension.
jlpm run watch
jupyter lab
With the watch command running, every saved change will immediately be built locally and available in your running JupyterLab. Refresh JupyterLab to load the change in your browser (you may need to wait several seconds for the extension to be rebuilt).
By default, the jlpm run build
command generates the source maps for this extension to make it easier to debug using the browser dev tools. To also generate source maps for the JupyterLab core extensions, you can run the following command:
jupyter lab build --minimize=False
Uninstall
pip uninstall jupyterlab-kernelspy
