Pylance works for .py files:

.py with pylance

But doesn't work with Jupyter .ipynb notebooks:

.ipynb with pylance

I tried saving the .ipynb - same issue.

How can enable Pylance warnings in my notebooks?

  • I don't think Pylance was built to work with notebooks. I would create a VS code interactive file instead. – Paul H Jan 05 '21 at 00:43

It seems that the Jupyter extension doesn't support Pylance.

I submitted this issue to address this shortcoming:

Pylance / Language server support #4307

I had this same problem and fixed by uninstall the jupyter extention and install the latest version of it.

Probably Tom has already solved your problem but if someone else is here looking for help that might solve it.

    reinstalling doesn't seem to have any effect. – Yar Mar 31 '22 at 21:49

In my case Pylance was ignoring imports and variables. Restarting the Jupyter kernel solved it.
