regret to inform you that image preprocessing and IO is done in either openCV or PIL or both for every image processing NN i’ve ever worked with.

Yes - not sure how this has been overlooked. For Python/torch I tend to use cv2 with an albumentations augmentation pipeline, which is much faster than PIL/torch transforms.

sometimes Pillow-simd is nice as well.

Thanks - I’ll check it out.
