Error ImportError: cannot import name 'MODEL_FOR_SEQUENCE_CLASSIFICATION_MAPPING' from 'transformers' (C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\transformers\__init__.py)
# 🐛 Bug

## Information

I am doing the tutorial ["Quick tour of the fine-tuning/usage scripts"](https://github.com/huggingface/transformers#quick-tour-of-the-fine-tuningusage-scripts)

I downloaded the Glue dataset.
When I try to run this command from pytorch
```
python ./examples/run_glue.py \
    --model_type bert \
    --model_name_or_path bert-base-uncased \
    --task_name MRPC \
    --do_train \
    --do_eval \
    --do_lower_case \
    --data_dir C:/Git/RemoteDGX/MRPC/glue_data/MRPC \
    --max_seq_length 128 \
    --per_gpu_eval_batch_size=8   \
    --per_gpu_train_batch_size=8   \
    --learning_rate 2e-5 \
    --num_train_epochs 3.0 \
    --output_dir /tmp/MRPC/

```
I am getting this error:
ImportError: cannot import name 'MODEL_FOR_SEQUENCE_CLASSIFICATION_MAPPING' from 'transformers' (C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\transformers\__init__.py)

## To reproduce

Steps to reproduce the behavior:

1.download the Glue database 
2. execute the script run_glue.py

this is the stacktrace:
```
