ValueError

[DirtyStreetCoder]

Hi,

stumbled upon autoviz and failed to run even a minimal example.

1) Had to change 'seaborn' to 'seaborn-v0_8' in AutoViz_Class.py and AutoViz_Utils.py 2) After that i got the error below, where i don't know how to proceed

Any suggestions or fixes?

Thanks in advance.

FYI: Here i used python 3.11.6. Had the same Error in python 3.11.4. Could not even install autoviz in python 3.12

I have the same issue with Python 3.10 but it works with 3.7

Ok @ConsciousML @DirtyStreetCoder : Let me see whether I can upgrade AutoViz to Python 3.10 version. I'll also have to check if importing hvplot and pyviz can be made within function calls so I can remove their versions from requirements.txt and setup.py files. It seems like hvplot and pyviz are changing too much for me to hold AutoViz to a consistent version. Give me a few days. Auto Vimal

Hey @ConsciousML @DirtyStreetCoder : I have some Good News! I have removed some references to Seaborn styles which have been deprecated. That seems to have fixed some issues. Can you please upgrade your AutoViz version to the latest version (0.1.735) and let me know whether your issues are fixed? Thanks Auto Vimal

Hi @DirtyStreetCoder @ConsciousML 👍 I have finally found the dependency problems with Python 3.10+ and fixed them I think. I have a new version 0.1.801 of AutoViz - please pip install and try it 👍 Thanks for your patience, Auto Vimal

[AutoViML]

@DirtyStreetCoder @ConsciousML 👍 I believe this is a problem between hvplot.pandas and the newer python versions such as 3.10 and 3.11

I suggest you try to uninstall and reinstall the correct version of hvplot.pandas that can work in your environments. If that install works and you can import it, it should be easy for AutoViz to also import it.

That's why I am closing this issue here. Please re-open it if there is an AutoViz related issue. Thanks Auto Vimal
