How good is the model generating these summaries? Can you provide any links to examples etc?

@olliestanley in my opinion the quality for the python model is pretty high, it generates a human-like response almost all of the times, perhaps you could argue it's a little bit short tho. Also, the code-search-net is a pretty easy dataset as all the functions include documentation so the output is usually a short version version of the docstring. I have also uploaded a version of the code-search-net with the summaries included if you want to check the quality output. The dataset can be found here
