python - Gensim example, TypeError:between str and int error

Question

When running the below code. this Python 3.6, latest Gensim library in Jupyter

for model in models:
       print(str(model))
       pprint(model.docvecs.most_similar(positive=["Machine learning"], topn=20))

Answer 1

string= "machine learning".split()

doc_vector = model.infer_vector(string)
out= model.docvecs.most_similar([doc_vector])

I'm not sure 100% since I'm using a more recent release, but I think that the issue is connected to the fact that the most_similar function is expecting a string mapped in the feature space and not the raw string.
