Hi,
I came across the following error when using label_from_folder
---------------------------------------------------------------------------

I read and splitted the data from a Dataframe.
My hunch that it is expecting a Path but for some reason got a str
Are there any assumptions for using label_from_folder?
(like creating the data from folder initially)
I’m using food-101 dataset which has a different structure than imagenet
I’ve this Notebook to show the complete steps I followed.
