[BUG] Colab produces error when zipping/downloading file and exporting model

[jaaaamIron]

Running Colab Pro+ and training via Google Drive (i.e. not web upload) when I finish training I get the following errors:

Exporting model...
Traceback (most recent call last):

FileNotFoundError: No files found matching the pattern '/content/gdrive/MyDrive/Colab/operative_config-*.gin'.

During handling of the above exception, another exception occurred:

UPDATE: It seems to be related to the file path - when I put everything in a folder on the top level of my drive it worked fine.

I experienced this too! The reason is that the 'Colab Notebooks' folder has a space in it. Spaces in folder names always crash the DDSP trainer. Notice that it looked for the config in '/content/gdrive/MyDrive/Colab/operative_config-*.gin'... it truncated the path to the correct folder at the space.

The solution is to modify the search pattern used to find the configuration file so that it doesn't treat whitespace as the end of the path.
