Missing links to source code in docs

I like browsing PyTorch docs but it would be nice if all the methods have a link to the corresponding source code. This is not the case though. For example, I wanted to take a look at torch.zeros implementation and went to https://pytorch.org/docs/stable/torch.html#torch.zeros. The source code link is missing as for many other functions, why?


Unfortunately these functions are implemented in c++ and so it’s not very easy to provide the source code for them directly from the doc.
Do you think cpp code would still be useful in the doc?
