Dataset Viewer issue
The dataset viewer is not working.
The error is thrown because dl_manager.download(url) returns original url instead of a path to downloaded file.
I added the following code to _generate_tables(self, file_path):
if file_path.startswith(_BASE_URL):
file_path = file_path[len(_BASE_URL):]
Not sure whether it can help. But I can't check it, because the dataset preview doesn't get updated after the change.
Are there examples of datasets.ArrowBasedBuilder usage?
Error details:
Error code: StreamingRowsError

Hi, @AresEkb , thanks for reporting.
Indeed, datasets library does not support pq.read_table in streaming mode yet... We should implement it.
You can remove the last code you added, e.g.:
if file_path.startswith(_BASE_URL):
file_path = file_path[len(_BASE_URL):]
In the meantime, you can circumvent this issue by passing a file-like object (instead of path name) to pq.read_table:
You can replace this line:
yield self.config.name, pq.read_table(file_path)
with
yield self.config.name, pq.read_table(open(file_path, "rb"))
Thanks for the help! I've changed the code.
However it seems that the dataset card not updated after the change. It still shows the exception.
I think that update broken few days ago. Is it possible to force it?
It's working now, thanks @albertvillanova and @AresEkb , for figuring out how to adapt the code:
I had to trigger the refresh manually. I'm investigating why it was not triggered automatically (it should have).
Thanks a lot for your help! It's great!
The issue with automatic refresh should have been solved now (https://github.com/huggingface/datasets-server/pull/676). Thanks for having alerted us about this issue!
