### Who can help?

@sgugger

### Information

- [X] The official example scripts
- [ ] My own modified scripts

### Tasks

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

### Reproduction

python run_ner.py \
  --model_name_or_path bert-base-uncased \
  --dataset_name conll2003 \
  --output_dir /tmp/test-ner \
  --do_train \
  --do_eval

Error: _raise DatasetGenerationError("An error occurred while generating the dataset") from e

### Expected behavior

Evaluation should run on pre-trained model on conll2003 dataset.
