Assumed bug in preprocess_ids

[etsnok]

In ontologies_embeddings.py in the method preprocess_ids, I assume that it's intended to collect the list of all ontology parents/ancestors. But wat it does instead is to take only the last ancestor. I guess correct would be something like:

 idxs.append(id_to_index[d.replace('_', ':')])

@etsnok yes! Great find. I updated the file!
