Loading custom music (ValueError: empty range for randrange())

[euneestella]

Hello, thanks for your amazing work!

I tried to use my custom music(.wav) to test the model following the README with the command python test.py --music_dir custom_music/. However, It raises ValueError. Can you get me how to manage this issue?

Thanks!

The test.py logic manages song lengths by taking random 30 second slices from each song. However, if your song is less than 30 seconds long, then the random choice will fail because there isn't enough music to pick from. That's what the error looks like to me, at a glance. Hope that helps.

Hello, in that case, is there any way to generate the motion for audio files that are shorter than 30 seconds?
