Add MedImg for streaming
@mariosasko, @lhoestq, @albertvillanova
Hello! Can anyone help? or can you guys suggest who can help with this? Hi ! Feel free to download the dataset and create a `Dataset` object with it.

Then your'll be able to use `push_to_hub()` to upload the dataset to HF in Parquet format and make it streamable :) > Hi ! Feel free to download the dataset and create a `Dataset` object with it.

The dataset is several TB in total, which I do not have the resources to handle. Hi @lhoestq and @albertvillanova , just following up about this. for big datasets you can push_to_hub one part at a time (e.g. as different splits) and merge the parts (just a simple modification in the YAML part of the README) Sure, that makes sense. However, isn't there a size limit to what typical users can push? Yes there is a limit, simply let us know by email at datasets [at] huggingface.co - this way we can give you a storage grant also help making sure the dataset is all good for people to use it easily > Yes there is a limit, simply let us know by email at datasets [at] huggingface.co - this way we can give you a storage grant also help making sure the dataset is all good for people to use it easily

Got it, that would be great.
### Feature request

Host the MedImg dataset (similar to Imagenet but for biomedical images). 

### Motivation

There is a clear need for biomedical image foundation models and large scale biomedical datasets that are easily streamable. This would be an excellent tool for the biomedical community.
