`deepcopy(first_layer)` creates temporary lazy tensors that, despite going out of scope at the end of the function, may not be garbage collected. Those tensors non-deterministically add to the graph captured by `torch_xla.sync()` and cause recompilations. TEST: torchprime E2E tests are red before this PR and goes back to green at this PR.
