Bug found in the script

Hi, This is a bug that I got when I tried to run the script.

This is what I got when I tried to run the script.

Python 3.10.5 Python Chess 0.25.1

Hi,

As the logs suggest, I don't think this is a bug from my program. As stated in the README, you need to install python-chess 0.23 using pip install python-chess==0.23.10. This tool needs to be rewritten for the latest version of python-chess but the API of the module keeps changing after each new version... I already updated the code once to use the latest version of python-chess at the time, but every update seems to break everything. IMO this is a bad design decision on their part as I think guaranteeing backward compatibility is important as a module owner.

Could you please try to install python-chess 0.23.10 instead to see if it fixes the error please ?

This is the error I am getting when I change the python-chess version

I didn't try to use this program with Python 3.10. It could be the root of the problem. If that's the case I will need to update this project to use the latest version of python-chess...

Sadly, I'm very busy at the moment but I will try to fix the problem within a month. The only temporary solution I can provide would be to use an older version of Python.

Thanks for the response! I appreciate you taking the time to provide answers though you are quite busy at the moment. You can please take your time and try to resolve this at a later point!
