Error in installing dependencies

I got the following error when installing cso-classifier:

I'm using Python 3.11, with Ubuntu 22.04

[akos326]

It seems that the required gensim 3.8.3 requires Python 3.8. However, the documentation leads me to download the latest version (3.11). Please correct the documentation

[angelosalatino]

Yes, python 3.8 works well. Thanks a lot for testing it.
