TypeError: int() argument must be a string, a bytes-like object or a number, not 'PngImageFile'

I've been using PyTorch FID to calculate FID over real/fake samples of pix2pix models. But its returning this error... each folder has 4k images of 256x256 pixels (.png)

Would I need to use imagemagick and try mogrify the images to convert them on jpg format?
