'Doc2Vec' object has no attribute 'wv'

Question

When I load doc2vec model from pkl file, I get this error.

Can you please help with the error?

What version of gensim was the model saved from, and what version are you loading it into? (The way word-vectors are stored inside the model has changed in recent versions.)

Generally gensim has tried to ensure old models load correctly, but some releases have had oversights in such backwards-compatiblity... so it is also worth trying the very-latest gensim, to see if it loads your older model without this error. (And if it gives the same error, report it as a bug on the project discussion list or Github project bug tracker.)
