System Info

Pytorch version: 2.8.0+cu128
Transformers version: 4.55.4

Who can help?

Hi,

I have uninstalled a latest version of transformers. While accessing "GptOssForSequenceClassification", I get the error:

ImportError: cannot import name 'GptOssForSequenceClassification' from 'transformers' (/home/user/miniconda3/envs/working/lib/python3.10/site-packages/transformers/init.py). @ArthurZucker

Information

• The official example scripts
• My own modified scripts

Tasks

• An officially supported task in the examples folder (such as GLUE/SQuAD, ...)
• My own task or dataset (give details below)

Reproduction

from transformers import GptOssForSequenceClassification

mdir='/home/user/gpt-oss-20b/'
model = GptOssForSequenceClassification.from_pretrained(mdir, [trust_remote_code=True)]
print(model)

Expected behavior

GptOssForSequenceClassification should be imported successfully.

I believe #40043 is not yet in a release, so you will need to install from source until then.

Installed from source:

In [1]: import transformers

In [2]: transformers.__version__
Out[2]: '4.56.0.dev0'

In [3]: from transformers import GptOssForSequenceClassification

Thanks, it worked now.
