where is the definition of _cudnn_convolution_full_forward in pytorch
as the title mentioned, I want to find the definition of _cudnn_convolution_full_forward, but I search through all the project
in pytorch and failed. And I cannot find and doc about this function.

any one can help me?

All the cudnn convolution functions are defined here:
https://github.com/pytorch/pytorch/blob/1848cad10802db9fa0aa066d9de195958120d863/aten/src/ATen/native/cudnn/Conv.cpp

This function doesn't exist anymore in the latest versions of pytorch. The closest thing that there is there is cudnn_convolution_forward. In version 0.1.12, the function is in the same file: 
https://github.com/pytorch/pytorch/blob/v0.1.12/torch/csrc/cudnn/Conv.cpp

I would recommend against using using an unpublic api (one starting with _) and use a public method instead, but you probably already know that.

In otherwords you should be using

torch.backends.cudnn.enabled = True


and then conv2d or conv3d depending on your use.
