doc.py file was built, but not reflected.

Hello. I have question about building documentation files.
I add some codes to _torch_docs.py file to solve the issue no. #29758 and built it.
Build was successful and I got an index.html file in build/html/folder, but the code I wrote was not reflected at all.
I tried a few times but couldn't solve it. Please give me a hand on which part to check.

I'm sorry, but @vishwakftw can you give me some advice?

I believe you have to rebuild PyTorch from source. The docs are built with the version of PyTorch installed, so if you don’t install PyTorch after making these changes, you won’t be able to see it.
