RuntimeError: No memory temporary dir found and fallback is disabled.

I configured the environment according to the document, and the above error occurred during the final training. What is the reason? I will be very grateful for your answer.

It is not able to find a tmpfs directory like /tmp.

To fix this, do any of the following:

1. Specify a temporary directory manually (preferably, but not necessarily, on a fast filesystem):

   tempfile = MemoryTempfile(preferred_paths=["/path/to/some/directory"])

2. Update to the latest git commit d4bf844, which now automatically falls back to the default tempfile if an error occurs.

The reason I used a temporary in-memory filesystem is because it can sometimes be faster than writing the intermediate .ply files to disk.
