How to retrive the results saved in model of gensim?
The question is not really clear. 

If the question is how can you save and retrieve the cosine-similarity of each word with every other word, then you can save them in an array and use pickle for saving and loading them again.

Or, If the question is how you can retrieve the gensim model, then the function is gensim.models.word2vec.Word2Vec.load()
