How can I one hot encode when creating a datablock?

I have a tabular dataset, and am currently passing the Categorify class as one of the processes to the procs parameter in the TabularPandas class.

I have searched the fastai docs to see if there’s anything for one hot encoding, but there doesn’t seem to be.

Does such functionality exist, or would I have to do it myself?

Finally, found a class for it, but I’m not sure how to use it. I’m passing it as an argument to the procs parameter.

Anybody knows how to use it?
