The program has an error message: ValueError: high <= 0

Very great work! It is a pleasure to communicate with you. I got the following error when I used make_spect_f0.py and make_metadata.py to train the model after processing my own dataset and then using main.py. Have you encountered it and how can I fix it?

Traceback (most recent call last):

    x_real_org, _, f0_org, len_org = next(data_iter)

high <= 0 means len(aa) - len_crop[0] <=0, which probably means aa is too short

Thank you very much for your answer, I have successfully solved the problem
