Hey @fkov - could you make sure that each field of your dataset (each value) is a dataset object, not a dataset dict object? You can follow the guide here for creating a custom audio dataset - Create an audio dataset
And then split it into train/test splits with - Main classes
Then your overall
dataset will be a dataset dict object (i.e. has splits), with each split a dataset object
you are right that was it, thank you.
