hvplot not working in vs code

I’ve just created a new virtual environment (.venv, python 3.10) with hvplot 0.8.2.

And it fails when I try to use it in the VS Code Interactive Jupyter window.

import hvplot.pandas

[Hoxbro]

The package has been yanked from pypi and marked as broken on conda-forge. A new release of ipykernel will be released at the start of next week. So I don’t think there is anything to do, other than wait.

[dwr-psandhu]

Downgrade worked.

Try to downgrade ipykernel to 6.17.1.

see #981
