5 years ago You are trying to train a model at a different sample rate than your audio files. You have three options:
1) Resample all of your audio files to your intended GAN sampling rate
2) Change the sample rate of the model with --data_sample_rate, which will change the length of the generated audio accordingly
3) Use librosa to load and resample audio files instead by removing the --data_fast_wav flag.
During handling of the above exception, another exception occurred:
