Data Loader error

Hi, Im trying to run the code with the COCO dataset, but I get an error when trying to extract the images from the data loader, specifically:

I have only changed the paths of the datasets, but somehow this error appears, do you know what It could be?

Hi,

I am also facing the same issue but I am using a custom dataset. Did you solve this issue? If so, Could you please help me?

Thanks, Bharaneeshwar.
