python and openCV installation

[snippsat]

I think you most remove this version.

c:\users\jost\appdata\local\programs\python\python38\

Try uninstall if not see it or always go into folder c:\users\jost\appdata\local\programs\python
Then delete folder python38,so only python38-32 folder is there.
Restart try again.

All goes wrong uninstall all Python versions and remove folders.
The can also choose a simpler path i always use simple path as eg C:\Python38\.
I don't like the long default Path,as i mention in tutorial here.

Also know that 64-bit version may be needed Download Windows x86-64 executable installer as many libaires in Opencv Data Science space requires it to use all optimizations.
Example look at this post,so example Taichi would not work with 32-bit.
So python38-32 means that's it's 32-bit.
