Hi @icozma :
This error seems related to Python 3.10 and higher. I am currently running on Python 3.7 and 3.8.
Let me see whether I can upgrade AutoViz to Python 3.10 version or higher. 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.
Hey @icozma 👍
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
I tried the Autoviz upgraded version, I stopped getting errors about seaborn (Python - 3.10.6, autoviz - 0.1.735), but the new error says:

This is similar to the original error posted
Hi @icozma
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,

Hi @RNarayan73 : As I have said this before, this is a problem between hvplot.pandas and Python version 3.11. Can you instead try installing and importing hvplot.pandas separately in your Oython 3,11 environment? That should take care of this problem!
As far I am concerned, this is a not a problem with AutoViz. I suggest you take it up in their forums.
Thanks

Hi all, I'm writing with respect to holoviz/hvplot#1239. This issue was fixed in holoviz/holoviews#5636 and released in HoloViews 1.16.0. It turns out this was all due to a change in Numpy itself, see numpy/numpy#23307.
AutoViz is pinning hvPlot and HoloViews to older versions but has no pin on Numpy:
Lines 30 to 32 in ba75e53
In my opinion your solutions include:
- using an older version of Numpy that is compatible with HoloViews <1.16.0
- update AutoViz to be compatible with HoloViews >= 1.16.0 (maybe it's already compatible and it's just about lifting the pin, but I don't really know)
As far as hvPlot is concerned, there isn't much we can do. In an ideal world we could backport this kind of bug fixes to older versions, but we really don't have the bandwith to do so, i.e. packages dependents on HoloViews have to use the latest version to benefit from the bug fixes.
@AutoViML, as suggested in the comment from the hvplot repository to the issues I posted there, this seems to be a problem with the incompatible, older versions of the dependencies used by autoviz.
Hope you will be able to fix it.
Hi @RNarayan73, @maximlt 👍
thank you all for the persistence and your helpful analysis.
I am going to pin the older version of numpy in this case numpy < 1.25.0
I feel that the later versions cannot be guaranteed to work with the rest of AutoViz and I would need to test extensively. I hope this works for your needs. Please upgrade to the latest version of autoviz and let me know.
Thanks
