State: closed
Labels: description: Something isn't working
name: bug

## Describe the bug
As reported on the Hub [Fix Checksum Mismatch](https://huggingface.co/datasets/mbpp/discussions/1), there is a `NonMatchingChecksumError` when loading mbpp dataset

## Steps to reproduce the bug
```python
ds = load_dataset("mbpp", "full")
```

## Expected results
Loading of the dataset without any exception raised.

## Actual results
```
