KeyError: "param 'initial_lr' is not specified in param_groups[0] when resuming an optimizer"

I'm trying to finetune 4.0-v2 using this checkpoint I found https://huggingface.co/cr941131/sovits-4.0-v2-hubert/tree/main
(not sure if its good or not)
But when I try to start training this error happens:

Traceback (most recent call last):
  File "/home/manjaro/.conda/envs/soft-vc/lib/python3.8/site-packages/torch/multiprocessing/spawn.py", line 69, in _wrap

    raise KeyError("param 'initial_lr' is not specified "
KeyError: "param 'initial_lr' is not specified in param_groups[0] when resuming an optimizer"

Where can I find official checkpoints if that one is bad?

Distribution of pretrained models is under planning.

For some scary reason, we removed the pre-training model, and there is currently no official way to get the pre-training model.
