This isn't an issue with the SMALViewer, rather this is caused because the CUDA modules of the pytorch port of neural renderer haven't been installed properly. Some things to check: make sure you have a recent GCC version installed e.g. I use gcc version 7.1.0. (test with gcc -v) and run the install with pip install neural_renderer_pytorch.

I recommend verifying neural renderer port has been successfully installed, e.g. by running their tests before proceeding with this one.
