Ask questionstrain_tacotron.py: Random CUBLAS_STATUS_INTERNAL_ERROR
Occasionally when training tacotron (
train_tacotron.py), CUDA throws an error and kills the training.

I don't know why this happens, it seems almost random. Sometimes it happens 12 hours after starting, sometimes it happens 15 minutes after starting.

Nice, that's a good solution. And yeah, I found out this morning that it picks up from where it left off very well. How many epochs did you leave it to train for? I'm on 100k so far and will probably let it run until close to a million I guess.
