Update your typing_extensions. – Isomer

Answer 1

Had the exact same problem, upgrading typing-extensions worked for me:

pip install typing-extensions --upgrade

Hurd

didn't work for me, had to downgrade bokeh to 2.3.3 – Varicolored

It might be worth to suggest using pip via Python's -m switch to target the correct Python version. Instead of pip, use python -m pip where python is the interpreter used for running the actual code. – Permit

In conda, use conda update typing_extensions. (Updated typing-extensions from 4.3.0 to 4.4.0 and worked!) – Cally

My black formatter was crashing in vscode with a similar output. This fixed it - thanks! – Dated

Answer 2

I got this error when I pip installed panel and hvplot in my conda environment. The previous replies didn't work for me, but reinstalling hvplot directly through conda worked like a charm!

conda install -c pyviz hvplot
