Hello,

I am trying to use:
https://www.rdkit.org/docs/source/rdkit.Chem.rdchem.html#rdkit.Chem.rdchem.ResonanceMolSupplier.GetNumConjGrps

But I keep getting this error message:

module 'rdkit.Chem' has no attribute 'GetNumConjGrps


I'd like to use this to find the conjugated group number as well as
their group size ( amount of bonds) to parse some structures.


Here's a snippet of my code


from rdkit import Chem


conjchaintest='c1ccccc1C=C-C(CC=C-C=Cc2ccc2)CC-C=CCC=C-C=C-C=C-C=C-C(c3ccccc3)'
m=Chem.MolFromSmiles(conjchaintest)
originalSanitized=Chem.SanitizeMol(m,catchErrors=True)
res=Chem.ResonanceMolSupplier(m)
groups=Chem.GetNumConjGrps(ResonanceMolSupplier(m))

And from here the error is given. I am using RDKit:2021.03.2. I'm not sure
what the issue is here because the documentation says that GetNumConjGrps
is a part of the Chem module. Am I calling it wrong?

Thanks,
