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

[LilacPeregrine]

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

I found a fix in #11

• the file path had a space in it, causing the issue.

If you have this issue in future, remove spaces!
