I have some proplem need your help

[ABcYsQ]

I made my own dataset according to your steps to replace the dataset for westtron, but I encountered a KeyError. These errors are all about labeling. My labels use uppercase letters. Do I need to change these labels to lowercase letters

These are related to the wetectron code, not mine. You can try lowercase or check the method they use in processing the dataset, I think I made some changes to the code but I don't have the code right now.
BTW, this method did not perform well in my one GPU training.
