3outeille/transformers backend (Dense model only) by 3outeille · Pull Request #2048 · pytorch/torchtitan

Context

This PR enables:

Llama-like HF models to work with 4D parallelism: FSDP, CP, TP, PP (and the combinations between them). The following models were tested:
- meta-llama/Llama-3.2-1B
- microsoft/phi-2
- Qwen/Qwen2.5-7B
- mistralai/Mistral-7B-v0.1
- ByteDance-Seed/Seed-Coder-8B-Instruct
- Qwen/Qwen3-4B-Instruct-2507
- arcee-ai/AFM-4.5B
- ibm-granite/granite-3b-code-base-2k
- baidu/ERNIE-4.5-0.3B-Base-PT
- kyutai/helium-1-preview-2b
- allenai/OLMo-7B-hf
- mistralai/Ministral-8B-Instruct-2410
Patching HF models weights initialisation. Without this, the the loss and grad_norm starts very high

Usage

Testing methodology

Following the converging.md guidelines, I am comparing the baseline FSDP=2 vs FSDP=2 & <other //-ism>
More precisely, the test_hf_integration.pyis going to do:

+                    nn.Identity() if use_identity_for_missing_modules else None


Could you quicly remind me why we need to use Identity() here?

I think it's because HF define their models without things like if toke_embeddings is None.

I still worry about such identities breaks DCP and could be the source of PP numerics issue. The concrete question is, when loading from seed checkpoint, are all the PP ranks restored perfectly?

cc @fegin if you know this definitively.

The concrete question is, when loading from seed checkpoint, are all the PP ranks restored perfectly?

Seems like PP ranks are restored perfectly because we have perfect match with Qwen but not with Llama for example (cf the screenshot at huggingface#4)

+
+def apply_fsdp(


By reading this function, the function is the same as the apply_fsdp function in llama4/parallelize (I know we will keep MoE capability for next PR), can we reuse the apply_fsdp function from llama4 and avoid keeping multiple copies?

Oh I see the difference - The only difference is moe_block = transformer_block.mlp line 337, in transformers models, the MoE module is named mlp, instead of moe. Can we use the same getter/setter way to rename it in model.py, so we can reuse the apply_fsdp function from llama4.

I don't have strong opinion on this, but I'm a little bit concerned if we have several copies, they will become diverged easily in the future

Valid concern. i'll reuse fsdp from llama3 for now as this PR handles only dense. It will make more sense to handle the getter/setter in the MoE PR

It sounds the changes are caused by specific ways transformers define models. Then let's fork the changed functions into experiments/transformers_backend/. I apologize for the back & forth.

but isnt the compromise good enough ? Copy pasting means not noticing changes in Pipeline parallel later on

For rotary_emb, torchtitan doesn't own the model definition, so has no visibility about this module and no guarantee on the correctness. That's why I think it's better for transformers_backend folder to own this function.

Regarding use_identity_for_missing_modules, I'm not convinced that it would work with DCP. If it's a transformers specific decision, we should also limit the scope of change to transformers_backend folder.

Thanks!

CI seems failing because of this -- should change to transformers_backend and specify --hf_transformers.model?

I'm not convinced that it would work with DCP. If it's a transformers specific decision, we should also limit the scope of change to transformers_backend folder.

Regarding identity not working with DCP, one easy way to know for sure will be to manually do if toke_embeddings is None in the Transformers modeling and see if the issue persists. Will add track it here huggingface#4
