How can I modify c++ files in pytorch?

How can I modify c++ files such as caffe2 or csrc c files? I can only find header files so that I can’t try to modify to test what I want.

Pytorch is calling methods from c++ files and I want to make changes in the c++ files such as caffe2/serialize/inline_container to test what I want to see.

I am totally lost as a starter and its been 2 weeks I am trying to get familiar with this software…

I beg your generousity.

You can find the inline_container.cc file here and it will have the same relative location in your locally closed GitHub repository.
Manipulate the file locally and rebuild PyTorch afterwards.

Thanks for answering! I was trying to follow the path according to the github path, but there are only headers… where can I find cpp files? I am using anaconda, would it be affecting?

You would need to git clone the repository, manipulate the file, and build PyTorch from source.
You cannot manipulate C++ files in a pre-built binary and expect to see changes without compiling the code again.

So… if I just download pytorch from their website in local or conda, I cannot find the cpp files, but headers? I have to clone their github and build pytorch by myself?

Yes, since C++ is a compiled language you would need to clone the repository and rebuild PyTorch from source. Any changes in .cpp files won’t be visible in the compiled binary.

Thanks a lot! And could you please let me know any resources about how to recompile those c++ files after making changes to apply for pytorch?

You can follow these instructions from the repository.
