Hi @albertvillanova. Unfortunately I still get this error. Is this because the merge has yet to be released? Is there a way to track the release?

Hi @thesofakillers, yes you are right: the fix will be available after next release (it was planned for today; Monday at the latest).

In the meantime, you can use the version of the `exams` on our main branch by passing `revision` to `load_dataset`:
```python
ds = load_dataset("exams", revision="main")
```
