0 charge for Hydrogens

[linpei26]

Hi!
I am so happy to find this tool.
Here is a simple question:
I test espaloma_charge + antechamber on a small molecule but found charges were 0 for all hydrogens.
As a comparison, using antechamber alone assign positive charges to all Hs.
The SMILES is
CC(C)(C)c1ccc(cc1)c2nnc(o2)c3cccc(c3O)OC ZINC001252803730_1
Could you please take a look?
Thank you!
