word2vec doc-comment example of KeyedVectors usage broken #2669
Description
The usage example in the word2vec.py doc-comment regarding KeyedVectors uses inconsistent paths and thus doesn't work.
If vectors were saved to a tmpfile-path based on the filename 'wordvectors.kv', they need to loaded from that same path, not some other local-directory file named 'model.wv'.
(Also, in my opinion the use of get_tmpfile() adds unnecessary extra complexity to this example. People usually don't want their models in a "temp" directory, which some systems will occasionally delete, so the examples might as well do the simplest possible thing: store in the current working directory with simple string filenames. The example code above this is also confused, because it creates a temp-file path, but then doesn't actually use it, choosing to do the simple & right thing with a local file instead.)
