[Feature] Keep the list of labels of a dataset as metadata
Yes! I see mostly two options for this:
- a `Feature` approach like currently (but we might deprecate features)
- wrapping in a smart way the Dictionary arrays of Arrow: https://arrow.apache.org/docs/python/data.html?highlight=dictionary%20encode#dictionary-arrays I would have a preference for the second bullet point. This should be accessible now as a feature in dataset.info.features (and even have the mapping methods). Perfect! Well done!! Hi,
I hope we could get a better documentation.
It took me more than 1 hour to found this way to get the label information. Yes we are working on the doc right now, should be in the next release quite soon.
It would be useful to keep the list of the labels of a dataset as metadata. Either directly in the `DatasetInfo` or in the Arrow metadata.
