separator argument ImageClassificationData.from_data_frame for multi label dataset

See original GitHub issue

🚀 Feature

for plant pathology kaggle dataset, after loading the csv/df with ImageClassificationData.from_data_frame I am getting dm.num_classes 11 but it should be 6.

There should be a way to pass how labels are separated in the df/csv - by space, comma or any other character.

Hi @aniketmaurya great suggestion! It’s worth noting that we don’t currently support this format at all. For multi-label, our CSV loading code assumes that each additional label is in a new column rather than a delimited string in a single column. Support for this, along with the ability to specify the delimiter, would be much appreciated. Is this something you would be willing to work on? The main class to be updated is here: https://github.com/PyTorchLightning/lightning-flash/blob/8f306d49b24aed09d37d083883f6c5636b26a45e/flash/core/data/data_source.py#L504

Closing this as plant pathology can now be loaded succesfully. We don’t support passing a seperator but it will be inferred and can be either a space or a comma 😃
