Adding new train_step logic to make things less confusing for users (#15994) * Adding new train_step logic to make things less confusing for users * DO NOT ASK WHY WE NEED THAT SUBCLASS * Metrics now working, at least for single-output models with type annotations! * Updates and TODOs for the new train_step * Make fixup * Temporary test workaround until T5 has types * Temporary test workaround until T5 has types * I think this actually works! Needs a lot of tests though * MAke style/quality * Revert changes to T5 tests * Deleting the aforementioned unmentionable subclass * Deleting the aforementioned unmentionable subclass * Adding a Keras API test * Style fixes * Removing unneeded TODO and comments * Update test_step too * Stop trying to compute metrics with the dummy_loss, patch up test * Make style * make fixup * Docstring cleanup * make fixup * make fixup * Stop expanding 1D input tensors when using dummy loss * Adjust T5 test given the new compile() * make fixup * Skipping test for convnext * Removing old T5-specific Keras test now that we have a common one * make fixup * make fixup * Only skip convnext test on CPU * Update src/transformers/modeling_tf_utils.py Co-authored-by: Sylvain Gugger <35901082+sgugger@users.noreply.github.com> * Update src/transformers/modeling_tf_utils.py Co-authored-by: Sylvain Gugger <35901082+sgugger@users.noreply.github.com> * Avoiding TF import issues * make fixup * Update compile() to support TF 2.3 * Skipping model.fit() on template classes for now * Skipping model.fit() on template class tests for now * Replace ad-hoc solution with find_labels * make fixup Co-authored-by: Sylvain Gugger <35901082+sgugger@users.noreply.github.com>
