Describe the bug I run the code below, but get the error. Can anyone help me?

Reproduction

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?

Environment

• OS: Ubuntu20.04
• GCC 11.1.0
• PyTorch version 1.13.1+cu117
  • How you installed PyTorch pip
  • GPU model 1080Ti
  • CUDA and CUDNN version 11.7
