nan loss during training

[dominicmini]

hi you, I'm trying to train model AdaSpeech from your project. However when I train pretrained model I get nan loss during training.
do you have any way to fix it from your code?

Yes, i'll update the newest code version to fix it soon. Because the new version of MFA tool make the preprocess code generate 0 frame for some phoneme.

in preprocessor/preprocess.py replace function average_mel_by_duration by this code:

Thanks a lot, I fixed it!
Do you have a pretrained model training on English or other language?

@tuanh123789 Hi bro:v Can you tell me about the effectiveness of the average_mel_by_duration function 💯

Hello, I encountered such a problem at the beginning, and now it has been solved. At the beginning, I made changes completely according to the pictures replied by the author. The preprocess.py 338 line still reported an error. Later, I deleted the last comma of the author, so preprocess.py would not report an error. Then you can train normally
