I am new to Python and found the following error with swmmtoolbox package. I would really appreciate your comments. Thanks

Traceback (most recent call last):

    from typing import Final, TypedDict, Literal, Protocol, **TypeGuard**, get_origin, get_args  # type: ignore

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

pip install typing-extensions --upgrade

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
