Description
Now uses a tempfile directory (
/tmp/random_hash/) instead of writing to/tmp/directly. This tmpdir is then immediately cleaned up by the context manager.Motivation and Context
This is because I was getting permission issues writing to the tmpfile directory on the cluster.
A big disadvantage is that this no longer caches the files anywhere. Probably it would be best to support a more permanant cache in some form (in which case this PR can be superseeded).
How Has This Been Tested?
I have successfully used the code.
Does this PR introduce a breaking change?
breaks the current caching behavior
