1. Change default parameters of --device to “cuda device”
   

2. Run the demo.py
   

[FlemingH]

If you print the 'torch.cuda.is_available()' before select_device function

Problem Solved

Problem Solved

And, why exactly is that?

@akashchgupta If you're having the same output, that's what I'm asking

1. Change default parameters of --device to “cuda device”
   
2. Run the demo.py
   

the 'Cuda available' is the description, you should choose from 0,1,2 or CPU. If you have only one GPU, then just use 0 as the default option.

A new possibility is that if your environment is anaconda, the default torch installation is the cpu version

This can solve the problem.
