How can I fix this? Tried Googling and it seemed to suggest issues with setuptools. But when trying to upgrade it shows it's already the latest version. It would be great if someone could help me fix this.

[skrowten-hermit]

@dbogdanov and @pabloEntropia Could you guys please give me a few pointers on how to fix this error?

[skrowten-hermit]

I don't know how, but the following seems to fix the above issue:

skrowten-hermit@HOLY-DIVER-W10LT:~/work/audioprism/lib/essentia$ sudo pip3 install --upgrade setuptools
