HVDM failing with NearestNeighbors

[panwarnaveen9]

When I am trying HVDM with NearestNeighbors, I am getting following error but on other hand HEOM working fine.

second question is, should I include label or class column index into categorical_ix or not ?

distance_function = HVDM(data, class_index, categorical_ix)
nbrs = NearestNeighbors(n_neighbors=15, algorithm='ball_tree', metric=distance_function.hvdm).fit(data)
dis_value, indices = nbrs.kneighbors(data)

I am keep on getting this error..

Hi @panwarnaveen9 , apologies for a very late response. I somehow forgot that issue and just seen it now again.

HVDM seems to have few bugs that were addressed by the users. If you can, please use HEOM instead. I will be addressing this issues after I come back from holidays!
