Stuck there when I run "python main_single_gpu.py datasets/" about two-stream-pytorch

Hi, there. The thing is, you may not have those optical flow images as I have.

As I wrote in here, if the code couldn't find the optical flow images, the program will stop and exit. So that is why no progress.

I suggest you change the setting files, e.g., train_flow_split1.txt according to your situation. Usually due to different video codec, we may have different number of RGB or optical flow images.

Hello, I add the data files but it reports below errors, do you have any suggestions?

Sorry, I don't know why such error occurs. I think it maybe due to different version of python or pytorch. I am modifying my code right now to achieve good accuracy on flow stream. I will test on different versions of pytorch to see if I can reproduce your errors.
