FileNotFoundError in Colab Demo

[PiotrMi]

Using the unmodified Google Colab Demo.
I think it has something to do with the zip file not being downloaded correctly. The size of the zip is only around 3KB. Maybe the Google Drive download is being rate limited?

Error:

Do you run the section 4 for downloading the model?

!sh scripts/download_model.sh

I've just checked the notebook, and still not found any problem.

[PiotrMi]

Yes, I ran the script. This is it's output:

Downloading...
Finish download.
Archive:  checkpoints.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of checkpoints.zip or
        checkpoints.zip.zip, and cannot find checkpoints.zip.ZIP, period.

Got the same issue when ran from localhost. But it works on Colab.

[Twenkid]

I am getting the error on Colab. I guess outdated link, and still I can't find another location.
