I met this problem when I tried to run the command CUDA_VISIBLE_DEVICES=0 python main_sr.py --cfg_path configs/training/swinir_ffhq512.yaml --save_dir save_dir_1 Could someone help me solve it?

It seems that opencv failed to read your image. Please have a try read your image with opencv.

Overload resolution failed:

• Can't parse 'params'. Sequence item with index 1 has a wrong type
• Can't parse 'params'. Sequence item with index 1 has a wrong type

It shows that there is a problem here, but I see that there is no problem with the code, can you tell me the version of opencv you are using

It solved. Thank you! It's a problem with the opencv version
