I made this mistake during training

I am getting the same error. Does not appear to affect training.

[AlexFeYang]

getting the same error, when I put a larger dataset(over maybe 76 images) will 100% get this error,
I meet the same error at ai-toolkit, it will kill the training process at the beginning
I think it is due to the gradio did not upload all the files(I check the dataset folder, it has only 76 while I upload 100 images)

I tried to train with 50 images and it worked, it seems there are too many images
Thank you
