I am using flair in my code and when I try to run it, it shows me this error:
ModuleNotFoundError: No module named 'flair'
When I try to install flair, it doesn't work. Someone please help. Thanks!

Okay, it works now! Had to uninstall everything, reinstall, then upgrape numphy package. Didn't have enough space on the drive as well so needed to upgrade that too.
Had another issue. Was running one of my commands and this error or

You can't pre-installed read-only uninstall torch, You can install different version in your home directory local files or create virtual environment.
