Error when running forward about chamferdistancepytorch

[Steve-Tod]

Hi guys, I found the cause of the problem.
I'm sharing the machine with others. Another person used JIT to compile a torch extension and created the directory /tmp/torch_extensions/. He has the ownership of this directory while I don't, so I don't have the permission to write into it. On another machine where /tmp/torch_extensions/ hasn't been created, everything goes on smoothly.

Hi @Steve-Tod,
Did you run the tests?
Cheers,

Hi, I run the unit_test.py and get the following results:

Jitting Chamfer 2D
Traceback (most recent call last):

BTW I Googled and found the error might be caused by incompatibility between pytorch 1.3.1 and Tesla V100-DGX I'm using.

@Steve-Tod
I think you can try this first. it may solve it.

Hi @jih189 , I use conda to create a new env with pytorch 1.3.1. I use cuda 10.0. In this new env, I clone this repo and run unit_test.py, and get 'PermissionError: [Errno 13] Permission denied: '/tmp/torch_extensions/' again.
