My target, tag_score_sizes, target_sizes was Variable of LongTensor, that caused problem when running. They needs to be Variables of IntTensor. For the last comment, I actually forgot to remove log_softmax in an earlier version without CTC and feed them directly into sigmoid and softmax. Now I put CNN + RNN + FC output directly to CTC. This makes result better than the last comment I posted. But it still doesn
t converge. You could refer to deepspeech 25 for CTC usage. That repo using CTC actually works. Still trying to find out how to make my model converge.
