Other than my line-comment highlighting some possibilities around the zero-case threshold & default-return, the core default-but-optional norming looks good! |

Follow-up from #3067:
This PR introduces an optional
KeyedVectors.wmdistance(norm=True/False)parameter. Users can now choose whether to normalize their embedding vectors in eachwmdistancecall or not.Prior behaviour:
gensim < 4.0: no normalization; user had to normalize all vectors explicitly manually (destructive operation).gensim == 4.0.0beta: normalize dynamically with each call =norm=Truehardwired.gensim > 4.0.0beta(this PR): defaultnorm=True, optionalnorm=False.
