AttributeError: module 'inspect' has no attribute 'isgenerator'

The latest version of librosa seems to errors out at import. Below is the full error message I get on pycharm

I tried to rollback to previous versions of librosa to see if that would solve anything but did not have any luck

@lostanlen You were right, my issue was caused by an old version of joblib (0.11). I upgraded it to 0.13.2 and now librosa 0.7.0 works. Thanks for your help. I will definitely look into using conda from now on.

@srubenacker upgrading from 0.5.1 to 0.7.0 is a pretty huge leap, so you are going to have to make sure that all of the other installed packages are also upgraded accordingly. In a conda environment, this would be automatic. My guess is that your installation of librosa interferes with other packages (in this case joblib). My advice is to always install librosa in a conda environment, unless you have a really compelling reason not to do so. If i were to debug your installation, the first command i would try is: which python3

and if it’s a pip python: pip freeze
