Attribute error when running train.py

[Zhi0467]

As the in title, I'm running into an AttributeError: can't set attribute when running train.py, is it because I'm using Python 3.8 or something is off with the passing of hparams?

You need to change the setup.py file to specifiy an old version of the package pytorch_lightning. Under 1.6 works for me
