Thanks for reporting, @nurik040404 .
Please note that the issue is not related to the dataset viewer, but to the data in your dataset: it can't be loaded
from datasets import load_dataset
ds = load_dataset("nurik040404/mse")
gives error:
ArrowInvalid: JSON parse error: Column(/comments/[]/score) changed from number to string in row 1
The datasets
loading script fails when trying to infer the data type of the comments score: sometimes they are numeric and some other times they are string (the empty string).
You should:
- Either edit the data content to make consistent the data type of the comments score
- Or implement a loading script and specify the appropriate data types using the
datasets.Features
