issue saving checkpoints of model

[wooae]

hello! when I try to train the model, I get the following error when the code tries to save the checkpoint:

Traceback (most recent call last):
  File "main.py", line 115, in <module>
    main()
  File "main.py", line 107, in main

    model_checkpoint_path = os.path.relpath(model_checkpoint_path, save_dir)
  File "/usr/lib/python3.7/posixpath.py", line 475, in relpath
    start_list = [x for x in abspath(start).split(sep) if x]
  File "/usr/lib/python3.7/posixpath.py", line 383, in abspath
    cwd = os.getcwd()
FileNotFoundError: [Errno 2] No such file or directory

I mounted my google drive into colab and am using colab to train the model. When I check my checkpoint folder, I have two files there but it appears that I am missing the checkpoint binary file and the .meta file. Any idea why this could be happening?

it seems that saving the checkpoints did not work consistently if I tried saving to a shared google drive folder, but worked if I saved to my own folder. closing the issue.
