DDSP training fails when training finished - zip file not found[BUG] #18

Closed LilacPeregrine closed 2 years ago

LilacPeregrine commented 2 years ago

I was attempting to train a new instrument on 18 minutes of audio in an mp3. When completed, I expected it to output a .zip file, but it did not. When I attempt to restart, it fails.

I completed this using Google Colab [https://colab.research.google.com/github/magenta/ddsp/blob/main/ddsp/colab/demos/Train_VST.ipynb] I do not know how to reproduce it, but I have tried twice with this audio, but it has worked on other audio before.

Here is the error: Zipping Complete! Downloading... Voice.zip You can also find your model at /content/gdrive/MyDrive/VST-DDSP/VST Voice2/ddsp-training-2022-07-23-0218/Voice
