create a new transform named like:
class ModuleMappingViaStringAndClassMatchTransform:
_module_mapping_via_class: Dict[Type[nn.Module], Type[nn.Module]]
_module_mapping_via_string: Dict[string, Type[nn.Module]]
@classmethod
def apply(cls, model):
transformed=False
for module in model.modules():
if repl_module := cls._module_mapping_via_class.get(type(module)):
# replace the class here
elif repl_module := cls._module_mapping_via_string.get(type(module)):
# replace the class here
Create two different dicts basically.
And write a test that makes sure the keys on the two dicts don't match.

can't we reuse existing method named get_num_layers_from_config and pass model.config.text_config to it?

In some models it is text_config, In some it is llm_config, txt_config etc. Hence adding it as a new function for vlm architecture

Let's keep it separate to avoid cluttering it with multiple conditions inside same function?

same comment as above is this new method required? Can't we reuse existing one?

please create different transform as mentioned above and separate this dict
| model_config["n_layer_text"] = 1 | ||
| model_config["n_layer_vision"] = 1 |

this should not go in library code. It is allowed only in tests

Already addressed in #267 |
5 participants
Features Added
1.Original modeling files removed for Intern. Generic Solution for Models not part of transformers.
2.Used Model Wrapper inside modeling files to put the generate_inputs functions. Calls will be made based on model at pretrained.
3.Constant file updated.
4.Removed pytorch generate from modeling_auto
5.General Clean up of code done
Tested and Verified on
