Accelerated 3D Depthwise Convolution

This is seperate repo of my pull request (Accelerated 3D Depthwise Convolution), which is part of Pytorch 1.9. This repo aim to support other people want to use the module without upgrade to latest cudnn or pytorch.

Installation

prerequisite:

• Pytorch >= 1.6
• Python3

python setup.py install

Usage

import torch
from depthwise_conv3d import DepthwiseConv3d

dtype = torch.float
conv = DepthwiseConv3d(2, 2, kernel_size=3, groups=2).to("cuda", dtype)
input = torch.randn(2, 2, 6, 6, 6, device="cuda", dtype=dtype).div_(2).requires_grad_()
output = conv(input)
