datasets.exceptions.DatasetGenerationError: An error occurred while generating the dataset
The error is for the config trait_segmentation
Maybe the solution is to rename segmentation_data.csv to metadata.csv, following https://huggingface.co/docs/hub/datasets-image? cc
@polinaeterna
if you have more details.
@severo , is there a problem with subsets that are different types? We've been seeing these issues with metadata files across datasets that have a mix of text and image subsets (ex: NEON beetles). We really appreciate your help trying to solve these issues!
is there a problem with subsets that are different types?
no, it's ok. splits must have the same set of columns, but not subsets.
@severo , thanks for confirming.
This is a similar error to the NEON beetles dataset, so I'm wondering if @lhoestq has a suggestion (pinged on that issue)?
I confirm the Viewer only supports metadata CSV files if they are named metadata.csv.
Btw if you want to check locally if a certain structure works, you can do
from datasets import load_dataset
ds = load_dataset("path/to/local/dir")
print(ds[0])

Ah, so when pairing images with CSVs containing info about them it has to be named metadata.csv even with yaml configs? Is there any plan to make this more flexible for datasets with multiple subsets to avoid the need to put a metadata.csv into each image directory where they are not as easily accessed? Even if it could just end in _metadata.csv or -metadata.csv, that would be very helpful to allow for more flexibility of dataset structure.
Also, thanks for the clarity on checking locally @lhoestq .

yes correct !

that would be great ! would be happy to discuss this on github https://github.com/huggingface/datasets

Thanks, @lhoestq . I've submitted an issue requesting such a feature and primed the discussion with my simplified suggested solution.
