Colab notebook error

[presentcreative]

I'm trying to create my own PICT files using the colab notebooks but I get to an error during main() of the second notebook.

Here are the errors:

any ideas?

Select "Reset all runtimes" and start over. Does it still reproduce after that?

[presentcreative]

Unfortunately the same errors show up after selecting Reset all runtimes.

Hi. I'm getting the same error. Its like is trying to find a checkpoint file to restore instead of creating a new one.

[0000marcosg]

Ok. I get it to run by setting the --checkpoint argument as None in default

parser.add_argument("--checkpoint", default = None, help="directory with checkpoint to resume training from or use for testing")

But I really dont know if im be able to restore a training session.

[keijiro]

Nice catch. You have to clear the checkpoint_dir argument in the settings section when you don't have any checkpoint to restore.

@0000marcosg You can restore a session with that argument. I used it a lot in the previous project.

[0000marcosg]

Yes, thank you! Just tested and is restoring the session.

Using 0000marcosg change and resetting all runtimes has solved this for me, thanks

setting checkpoint dir to None in the parser fixed it for me as well.

Thank you for the awesome work!
