The Variable Inspector is a Jupyter Lab extension designed to help you manage and track variables within your notebook. It displays all your variables in one convenient location, allowing you to see their names, values, types, shapes, and sizes in real-time. This feature makes it easier to work without the need to manually print or check your variables. It is for Python only..
Install the extension using pip by following the instructions below. It’s also available in our desktop app, MLJAR Studio, which is designed to make Python easier for beginners.
Explore all available variables in the current notebook as a list.
You can preview the DataFrame values as an interactive table.
The preview of DataFrame will be automatically refreshed when you change it in the Python code.
You can select which properties of the variables you'd like to display:
The list of variables will automatically update whenever you execute a cell. However, you can choose the Manual Refresh option to update the list at your convenience.
If you prefer a darker look, a Dark Theme is also available!
- JupyterLab >= 4.0.0
To install the extension, execute:
pip install variable_inspectorTo remove the extension, execute:
pip uninstall variable_inspectorNote: 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.
# Clone the repo to your local environment
# Change directory to the variable_inspector directory
# Install package in development mode
pip install -e "."
# Link your development version of the extension with JupyterLab
jupyter labextension develop . --overwrite
# Rebuild extension Typescript source after making changes
jlpm buildYou 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.
# Watch the source directory in one terminal, automatically rebuilding when needed
jlpm watch
# Run JupyterLab in another terminal
jupyter labWith 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 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=Falsepip uninstall variable_inspectorIn development mode, you will also need to remove the symlink created by jupyter labextension develop
command. To find its location, you can run jupyter labextension list to figure out where the labextensions
folder is located. Then you can remove the symlink named variable-inspector within that folder.
