Dependencies sometimes fail to mount

[nelson-liu]

This bundle failed because it failed to find a script in a dependency at the path that it expects: https://codalab.stanford.edu/bundles/0xf8b9bd36e8bd4d8ead256f168a2c42b3

However, mimic-ing the bundle led to success: https://codalab.stanford.edu/bundles/0xdaffe96a8cfa409ebd1f35197b5623c2

It seems like sometimes, dependencies aren't being mounted properly?

Wasn't able to view this, since I don't have access

How reproducible is this?

[nelson-liu]

i haven't put much effort into reproducing it, but it doesn't happen that often.

I think this is related to #1417 , so I'm going to link them. In this bundle ( https://codalab.stanford.edu/bundles/0x28e3f9b40be745acad20c7cb448b0b66 ), I run:

python dependency/script.py ; python dependency/script.py 

The first invocation works without any issues, but on the second one, python complains that dependency/script.py doesn't exist.

Seems like it happens more when using worksheets.codalab.org with NLP workers?

Closing in favor of #3627.
