What might cause
lr_find to hang up without completing?
It gets stuck in this state and won’t go any further.
Fit does the same thing. I’ve run the model successfully numerous times on the Kaggle Freesound competition data. Now, I’m trying to develop pre-trained weights using Audioset data, but can’t figure out what’s going wrong.
There’s no stack trace, so I can’t run debugger. I’ve tried smaller batch-sizes thinking it might be a memory issue. It didn’t help. Perhaps there’s a problem with the data, but if so, why would I not get an error message?
Most of the Audioset files are in mono format, but some are 6-channel. That caused me some problems initially, but I was able to load all the files in (all with same shape array) and compute mean and standard deviation. I had to develop my own versions of
transforms.py because this is audio data, but as I said, I’ve run them successfully many times on the Freesound data.
Any ideas about what might be going on?
