I'm getting an error when I try to create the dummy data:
```python
aclifton@pop-os:~/data/hf_datasets_sprint/datasets$ python datasets-cli dummy_data ./datasets/logiqa_en/ --auto_generate

``` Hi ! Sorry for the delay

To fix your issue for the dummy data you must increase the number of lines that will be kept to generate the dummy files. By default it's 5, and as you need at least 8 lines here to yield one example you must increase this.

You can increase the number of lines to 32 for example by doing
```
datasets-cli dummy_data ./datasets/logica_en --auto_generate --n_lines 32
```

Also it looks like there are changes about other datasets in this PR (imppres). Can you fix that ? You may need to create another branch and another PR. To fix the branch issue, I went ahead and made a backup of the dataset then deleted my local copy of my fork of `datasets`. I then followed the [detailed guide](https://github.com/huggingface/datasets/blob/master/ADD_NEW_DATASET.md) from the beginning to reclone the fork and start a new branch. 

However, when it came time to create the dummy data I got the following error:
```python

KeyError: "Some Cantonese don't like chili, so some southerners don't like chili."
``` Hi ! The error happens when the script is verifying that the generated dummy data work fine with the dataset script.
Apparently it fails because the text `"Some Cantonese don't like chili, so some southerners don't like chili."` was given in a field that is a ClassLabel feature (probably the `answer` field), while it actually expects "a", "b", "c" or "d". Can you fix the script so that it returns the expected labels for this field instead of the text ?

Also it would be awesome to rename this field `answerKey` instead of `answer` to have the same column names as the other multiple-choice-QA datasets in the library :)  Ok getting closer! I got the dummy data to work. However I am now getting the following error:

``` Hi ! It looks like the version of `datasets` that is installed in your environment doesn't match the version of `datasets` you're using for the tests. Can you try uninstalling datasets and reinstall it again ?
```
pip uninstall datasets -y
pip install -e .
``` Closer still!
