I have carefully followed the instructions in  #5264  but still get the same error.

### Steps to reproduce the bug

``` 
from datasets import load_dataset

dataset = load_dataset("laion/laion-coco", ignore_verifications=True/False)
```

### Expected behavior

Properly load Laion-coco dataset

### Environment info

datasets==2.11.0 torch==1.12.1 python 3.10

Comments: This can also mean one of the files was not downloaded correctly.

We log an erroneous file's name before raising the reader's error, so this is how you can find the problematic file. Then, you should delete it and call `load_dataset` again.

(I checked all the uploaded files, and they seem to be valid Parquet files, so I don't think this is a bug on their side)
