Reproduction Hello, I made the environment by Docker like this page.

  1. What command or script did you run? 
    python tools/demo.py configs/elephant/cityperson/cascade_hrnet.py ./models_pretrained/epoch_5.pth.stu demo/ result_demo/
  2. Did you make any modifications on the code or config? Did you understand what you have modified?
  3. What dataset did you use?

I think the problem is related to your PyTorch and mmdetection versions. A similar issue was opened here. Check installation.md file for version references.
