## Information

Model I am using (Bert, XLNet ...):  huggingface/distilbert-base-uncased-finetuned-mnli - microsoft/deberta-v2-xxlarge-mnli - roberta-large-mnli -  squeezebert/squeezebert-mnli - BERT-Base-MNLI....

The problem arises when using:
* [x] the official example scripts: (give details below) 
* [ ] my own modified scripts: (give details below)

The tasks I am working on is:
* [x] an official GLUE/SQUaD task: (give the name)
* [ ] my own task or dataset: (give details below)
 
I use run_glue.py on fine-tuned models to reproduce the evaluation result (only `--do_eval`). But the accuracy is about 7%. Other tasks like MRPC or STS-B are ok when I use their fine-tuned models.
## To reproduce

Steps to reproduce the behavior:

1. Run `python run_glue.py --model_name_or_path huggingface/distilbert-base-uncased-finetuned-mnli --task_name mnli --do_eval --max_seq_length 128 --output_dir temp/distill` or any other MNLI fine-tuned model. I even tried a model that I fine-tuned myself using V2.10.0 and that again results in 6%-7% accuracy.

## Expected behavior

<!-- A clear and concise description of what you would expect to happen. -->
It seems all the weights are loaded in the correct place, but the accuracy is below 10% which should be above 80%.

If your task is similar to the task the model of the checkpoint was trained on, you can already use DistilBertForSequenceClassification for predictions without further training.

Comments:
Hello! This may be because of labels being switched around for the MNLI task. See this thread https://github.com/huggingface/transformers/pull/10203 for more context.

Hello, 
Many thanks for your response. Yes, that seems to be the source of my issue, and now I can get the accuracy. 
Thanks!


I think there is also a specific problem in `huggingface/distilbert-base-uncased-finetuned-mnli`: its labels seem wrongly coded. Using them specifically and evaluating gives me 34% accuracy.

Yes. But other models seem to work with the modification that I made https://github.com/huggingface/transformers/pull/10203#discussion_r582971857

@sgugger Can someone fix this, or remove the model from the model hub? This is a serious gotcha and cost me a couple weeks of confusion!

The model has been fixed a year ago, in [this commit](https://huggingface.co/huggingface/distilbert-base-uncased-finetuned-mnli/commit/0fadb1fe60cd119b3af82e2bf9cb98a59336d7bc)

Thank you for clarifying @sgugger! I think we had an old copy
