Engine.py error

This error shows me in engine.py in function train_one_epoch(), but I think that I don’t need to change this script. Because of function _get_image_size() in transforms.py I was downgrade torchvision to 0.10.0 and torch = 1.10.0 but now this error shows me and I don’t know if the problem is because of versions or something else ?

I followed this tutorial TorchVision Object Detection Finetuning Tutorial — PyTorch Tutorials 1.12.1+cu102 documentation and I’m wondering which versions are used here ?
