Error running demo.py: TypeError: 'NoneType' object is not subscriptable

[horanyinora]

Hello,

I am trying to run the demo file on the teaser image. I followed the instructions of #4 because I had the same error as #1. I am a bit confused about the downloads. Particularly:

• Downloading the SMPL model from my Google Drive
• Downloading neutral model .pkl from smplify_code_v2.zip
  I cannot seem to find smpl.zip anywhere therefore I used the .pkl file from the simply_code_v2 under data/smpl/. The code seems to run now however, even tho I get prediction results but the output of prepare_dump is None. This is my output:

WARNING: You are using a SMPL model, with only 10 shape coefficients.

I commented the try-except part (demo.py line 89-94) to get a more detailed error message. The problem seems to occur in renderer.py line 88:

During handling of the above exception, another exception occurred:

Hi! I have the same problem. Have you solved this problem? If so, would you mind sharing the solution?
