On 2.1, I am getting backend errors atm. For instance, with the unet: > torch._dynamo.exc.BackendCompilerFailed: backend='hidet_backend' raised: NotImplementedError: hidet: Tensor.to(..., device=...) is not supported for symbolic tensors... Early torch 2.0 was full of backend unimplemented/unsupported errors too, but I can't even remember when that was all implemented and the dynamo issues popped up (or even when everything started working) since I stayed on torch nightly.
