Hi, I need to implement a convolution layer with cuda. I read the code in pytorch sources here: https://github.com/pytorch/pytorch/blob/master/aten/src/THCUNN/SpatialDepthwiseConvolution.cu 3. However I did not find its  interface that I can invoke in python? I have also looked for it in the legacy interface, it was not there either. Where did it go?
Thanks in advance.
