Thanks for reporting !
#2433 fixed the issue, thanks @mariosasko :)

We'll do a patch release soon of the library.
In the meantime, you can use the fixed version of adversarial_qa by adding `script_version="master"` in `load_dataset`
## Describe the bug
A clear and concise description of what the bug is.

## Steps to reproduce the bug
```python
dataset = load_dataset('adversarial_qa', 'adversarialQA')
