1558263 : jupyterhub matplotlib widget¶

Created: 2025-12-04T07:25:04Z - current status: new¶

Anonymized Summary: A user ([USERNAME]) is experiencing issues with interactive plots in JupyterHub using matplotlib. The %matplotlib widgets command is not working, and attempts to install jpympl in their Conda environment have failed. The user has attached a screenshot of their JupyterLab extensions.

Solution: 1. Ensure that the ipympl package is installed in the correct Conda environment. The user should verify that they are using the right environment when launching JupyterHub. 2. Check for compatibility issues with other installed packages, as conflicts can prevent ipympl from working properly. Avoid installing packages in ~/.local and instead use a Conda environment. 3. If the issue persists, the user may need to configure JupyterLab to enable interactive widgets by setting the appropriate environment variables (e.g., JUPYTERLAB_DIR=~/.jupyter/lab).
