Do you know how I could fix this? I am trying to use benjiebob/SMALViewer#3 1 repo however I get error on neural_renderer port:
$ python smal_viewer.py 
Traceback (most recent call last):
  File "smal_viewer.py", line 2, in <module>
    import pyqt_viewer

ImportError: /home/mona/anaconda3/lib/python3.7/site-packages/neural_renderer/cuda/load_textures.cpython-37m-x86_64-linux-gnu.so: undefined symbol: THPVariableClass

Here is some details:
