ValueError: unsupported pickle protocol: 5 #29

@romainsacchi Good day Mr. Sacchi, after installing the new version of carculator (1.8), unfortunately I get the value error "unsupported pickle protocol: 5" directly right after import carculator command.

The package from conda install -c romainsacchi carculator looks like has some version control problem, then I decided to install the package from PyPi but looks like the problem is still there.

I would appreciate any help regarding this issue

Hello,

I think this might be a python version issue. Are you using Python 3.8 or lower? If so, could you try in a new environment with Python 3.9 or 3.10?

Also, try to install carculator 1.8.1 instead of 1.8.0.
