load_dataset("multi_woz_v22") NonMatchingChecksumError
Author: Vincent950129

Hi, it seems that loading the multi_woz_v22 dataset gives a NonMatchingChecksumError.

To reproduce:

`dataset = load_dataset('multi_woz_v22','v2.2_active_only',split='train')`


This will give the following error:

```
    raise NonMatchingChecksumError(error_msg + str(bad_urls))
datasets.utils.info_utils.NonMatchingChecksumError: Checksums didn't match for dataset source files:

Comments: Thanks for reporting !
This is due to the changes made in the data files in the multiwoz repo: https://github.com/budzianowski/multiwoz/pull/59
I'm opening a PR to update the checksums of the data files.

I just merged the fix. It will be available in the new release of `datasets` later today.
You'll be able to get the new version with
```
pip install --upgrade datasets
```

Hi, I still meet the error when loading the datasets after upgradeing datasets.

raise NonMatchingChecksumError(error_msg + str(bad_urls))
datasets.utils.info_utils.NonMatchingChecksumError: Checksums didn't match for dataset source files:
['https://github.com/budzianowski/multiwoz/raw/master/data/MultiWOZ_2.2/dialog_acts.json', 'https://github.com/budzianowski/multiwoz/raw/master/data/MultiWOZ_2.2/test/dialogues_001.json']

This must be related to https://github.com/budzianowski/multiwoz/pull/72
Those files have changed, let me update the checksums for this dataset.

For now you can use `ignore_verifications=True` in `load_dataset` to skip the checksum verification.
