shouldn't this be handled by _prepare_for_class? Especially as it would avoid this hard-coded 3, 5

Happy to, but inputs_embeds does not seem to be tested (AFAIK it is not in general in prepare_config_and_inputs_for_common). Do you suggest to edit all the tests/models/**/test_modeling_*.py to get inputs_embeds?

Won't this clash with input_ids in the inputs?

No as we add a new set of inputs to test, independent of the previous that uses input_ids.

My understanding of the test set-up is that the inputs to the model will now include both input_ids and input_embeds, which shouldn't be the case.

No, inputs_to_test is a list of dict, with each dict being one input to the model.

what about mamba here? uses cache_params 😅

mamba is afaik not supported in symbolic_trace

Hi @fxmarty Could you take a look on the following (see https://app.circleci.com/pipelines/github/huggingface/transformers/97223/workflows/f7cf9ddb-909b-4544-994a-18aaadbb77ac/jobs/1286547)? FAILED tests/models/blenderbot_small/test_modeling_blenderbot_small.py::BlenderbotSmallModelTest::test_torch_fx - ValueError: You have to specify either input_ids or inputs_embeds |
We should prompt users to use
torch.export.exportinstead.Fixes #31414
Fixes #31200
