Do you know how I could fix this? I am trying to use benjiebob/SMALViewer#3 repo however I get error on neural_renderer port:
$ python smal_viewer.py
Traceback (most recent call last):

I was able to fix this by first finding all the AT_CHECK and converting them to AT_ASSERT. Checking out the at_assert_fix didn’t solve the problem for me. I am using PyTorch 1.6 and CUDA 10.1
