Cannot load the dataset conll2012_ontonotesv5
MEMBER
Hi @cathyxl, thanks for reporting.

Indeed, we have recently updated the loading script of that dataset (and fixed that bug as well):
- #4002

That fix will be available in our next `datasets` library release. In the meantime, you can incorporate that fix by:
- installing `datasets` from our GitHub repo:
```bash
pip install git+https://github.com/huggingface/datasets#egg=datasets
```
- forcing the data files to be redownloaded
```python
ds = load_dataset('conll2012_ontonotesv5', 'english_v4', split="test", download_mode="force_redownload")
```

Feel free to re-open this issue if the problem persists.
