Evaluate QA models using run_qa.py script
The same command given in the README without the training prompts works perfectly. Just tried:
```
python examples/pytorch/question-answering/run_qa.py \
  --model_name_or_path deepset/deberta-v3-base-squad2 \
  --dataset_name squad \
  --do_eval \
  --max_seq_length 384 \
  --doc_stride 128 \
  --output_dir ~/tmp/debug_squad/
```
And it proceeds without error to an F1 of 92.28 and accuracy of 85% for exact matches.<|||||>You will need to adapt the example (which is just that, an example) to the format of your own data.
