Would it be possible to use chemprop as the fingerprint?

I don't know how yet, but I guess a pretrained chemprop model (CHEMELEON it is called) could be used for molecular encoding/vectorization.

I wonder how it would compare to classical fingerprints.

How easy is it to add a new fingerprint/encoding function that would not be calculated by rdkit?

Is there an example of a custom molecular encoding function?

I understand that's a 2048 float fingerprint.

Ok, so the code allowing to do that is here:
