ImportError: cannot import name '__version__' from 'sklearn' (unknown location)

Question

Windows laptop, using jupyter notebook

because of other errors I was having, I recently had to uninstall and re-install a bunch of packages (pip, jupyter notebook, tensorflow, sklearn + don't remember the others but all were python related). Now, I'm getting this error. Anyone know how to fix it? Thanks!

Also, not sure if this is related, but I get the following warning in my commandprompt everytime I try to install a program.

WARNING: Ignoring invalid distribution -umba (c:\users\user\anaconda3\lib\site-packages)

Answer 1

So, turns out the warnings I was getting were related to the import error. I went into the site-packages directory & deleted all folders with ~ in front of them & then my code worked.
