RuntimeError: DataLoader worker (pid 16126) exited unexpectedly with exit code 1

Sorry to bother you but I had another issue when I tried to train with my own data sets: python main.py --mode='train' --train_path='data/images' --label_path='data/ground_truth_mask' --batch_size=8 --visdom=False

It seemed to run correctly as first, but then came the error:

I really appreciate your generous help!

please check your own image and label directory：is there are some "not picture" file in this directory （I try the training in my computer, without the error you meet.）

[Kyle0936]

Here are my image set and ground truth set. I also have used "ls -a" to check and have removed '.DS_Store'. The only not picture files left are '.' and '..', which clearly should not be deleted. Are there any requirements for the names or forms of images?
