Pytorch 2.0 compiled models fail when used with fastai. Two fixes are necessary to run a basic Convnext model.
fastcore L.eq requires a chack for a function being passed in, and the Flatten layer has to have the Tensorbase type cast removed.
After this a simple model=torch.compile(model) increases training throughput (it/s) by 50%+.
The compiled models can't have layers frozen/unfrozen, so the train head / train all strategy is not useable, but didn't make much difference in my limited tests.
