Create and Expose SamVisionModel as public for better accessibility by geetu040 · Pull Request #36493 · huggingface/transformers

What does this PR do?

This PR makes SamVisionEncoder publicly accessible while keeping its name unchanged. This improves usability by allowing users to instantiate the vision encoder directly, similar to how SamModel is used.

from transformers import SamVisionConfig, SamVisionEncoder
config = SamVisionConfig()
model = SamVisionEncoder(config)

Hi @qubvel and @zucchini-nlp

I have updated SamVisionEncoder to make it public, but I am having a problem making TFSamVisionEncoder public.

First, I am not even sure, if it is necessary to have TFSamVisionEncoder public, I am just following the test utils/check_repo.py which fails to find TFSamVisionEncoder

TFSamVisionEncoder saves the vision layers in attribute self.layers, this works fine when TFSamVisionEncoder inherits from keras.layers.Layer but fails when inherited from TFPreTrainedModel which inherits from keras.models.Model. Because keras.models.Model already has layers as a read-only-property.

Changing the name would break backward compatibility, we can either:

completely disregard the idea of making SamVisionEncoder public and use modular where it is needed as backbone (in context of Deepseek-VL #36248).
make SamVisionEncoder public and leave TFSamVisionEncoder as it as, and exempt this from relevant tests.

zucchini-nlp

LGTM overall!

For the TF model, you mean making the model a PreTrainedModel is causing issues or just making it public (i.e. adding in high level init)? I am not very familiar with TF models in transformers, but I think we can figure out a way. Maybe @qubvel has more expertise on that?

Keeping SamVIsionEncoder as pre-trained model is important, if we want to use it as vision backbone with VLMS. Especially useful for setting different load-time configuration for each backbone.

I have added TFSamVisionEncoder to __init__, that fixes the failing check.

Though TFSamVisionEncoder still doesnot inherit TFSamPreTrainedModel and therefore is not added to auto modeling.
Fails to inherit because #36493 (comment)

TFSamVisionEncoder saves the vision layers in attribute self.layers, this works fine when TFSamVisionEncoder inherits from keras.layers.Layer but fails when inherited from TFPreTrainedModel which inherits from keras.models.Model. Because keras.models.Model already has layers as a read-only-property.

And by the way SamVisionEncoder works all fine. To conclude everything:

SamVisionEncoder

imported in __init__, available via from transformers import SamVisionEncoder
part of auto modeling
imports PreTrainedModel
available in docs

TFSamVisionEncoder

imported in __init__, available via from transformers import TFSamVisionEncoder
not part of auto modeling
doesnot import PreTrainedModel
not available in docs

The failing checks at ci/circleci: tests_torch are fixed in #36422.

Thanks for the update, just a small nit to make it simpler and reuse existing code

Hello @qubvel, a soft reminder for review

qubvel · 2025-03-26T10:18:20Z

Thanks for the ping @geetu040, will review today

qubvel

Ok, looks good to me! Thanks for working on it.

P.S. Test failures are unrelated.
