Hi, we are having a problem with the code. When we copy python main.py --ni --config imagenet_256.yml --doc imagenet --timesteps 20 --eta 0.85 --etaB 1 --deg sr4 --sigma_0 0.05 in the prompt this is the error that occurs:

Can somebody help us? We are new to coding, so we don't know where to start. Thank you very much
