Backbone path?

[clyy21]

Hi, thank you for sharing this PLIP model! It is a great work! However, I am a newbie in model training and would like to seek some help from you.

I am confused about what the PC_DEFAULT_BACKBONE in the config.env file should be. I assumed it should be a pre-trained model, so I assigned it with the path to the model but it seems like I am wrong. I am trying to run the fine_tune_training.py but now I do not know how to continue further. Could you give me some assistance? I would appreciate that! :)
