"at" has no member "cudnn_convolution_xxx"

C++

Hello there,

I’m using pytorch 1.12 to compile a custom operator and I found that
at::cudnn_convolution_backward_weight is missing which is supposed to be in include/ATen/NativeFunctions.h.
So I got the following error:

namespace "at" has no member "cudnn_convolution_backward_weight"

I search the include directory and only found a function named at::convolution_backward.

Am I suppose to use this function instead of at::cudnn_convolution_backward_weight ? Is there any documentation for me? I couldn’t find any clue in release note.

Thanks!

The cudnn calls are not exposed anymore if I’m not mistaken, so use the plain convolution functions instead.

Thanks! I refer to code here to solve my problem.

For those people who are stucked by this problem, plz use the convolution_backward instead of cudnn_convolution_xxx. Or you could use torch < 1.11.0 to compile your operator.
