Hi, everyone,
When I writing cpp extension using cudnn_convolution_backward, I meet Cudnn Error. My cpp extension looks like this:
#include <torch/extension.h>
#include <ATen/NativeFunctions.h>
#include <ATen/Config.h>
#include <cstdio>
#include <iostream>
#include <array>


at::Tensor conv2d(
    const at::Tensor& input,
    const at::Tensor& weight,
    const at::Tensor& bias,
    int64_t stride_weight,
    int64_t stride_height,
    int64_t padding_weight,
    int64_t padding_height,
    int64_t dilation_weight,
    int64_t dilation_height,
    int64_t groups,
    bool benchmark,
    bool deterministic) {

    std::array<int64_t, 2> arr_stride{stride_weight, stride_height};
    std::array<int64_t, 2> arr_padding{padding_weight, padding_height};
    std::array<int64_t, 2> arr_dilation{dilation_weight, dilation_height};

    c10::IntArrayRef stride(arr_stride);
    c10::IntArrayRef padding(arr_padding);
    c10::IntArrayRef dilation(arr_dilation);

    // printf("--------------------------------hello conv2d----------------------------------------\n");

    return at::cudnn_convolution(
        input,
        weight,
        bias,
        padding,
        stride,
        dilation,
        groups,
        benchmark,
        deterministic);
}

std::tuple<at::Tensor, at::Tensor, at::Tensor> conv2d_backward(
    const at::Tensor& self,
    const at::Tensor& grad_output,
    const at::Tensor& weight,
    int64_t stride_width,
    int64_t stride_height,
    int64_t padding_width,
    int64_t padding_height,
    int64_t dilation_width,
    int64_t dilation_height,
    int64_t groups,
    bool benchmark,
    bool deterministic,
    std::array<bool, 3> output_mask) {

    // printf("--------------------------------hello conv2d backward----------------------------------------\n");
    
    std::array<int64_t, 2> arr_stride{stride_width, stride_height};
    std::array<int64_t, 2> arr_padding{padding_width, padding_height};
    std::array<int64_t, 2> arr_dilation{dilation_width, dilation_height};

    c10::IntArrayRef stride(arr_stride);
    c10::IntArrayRef padding(arr_padding);
    c10::IntArrayRef dilation(arr_dilation);

    return at::cudnn_convolution_backward(
        self,
        grad_output,
        weight,
        padding,
        stride,
        dilation,
        groups,
        benchmark,
        deterministic,
        output_mask);
}

PYBIND11_MODULE(TORCH_EXTENSION_NAME, m) {
    m.def("conv2d", &conv2d, "2d convolution");
    m.def("conv2d_backward", &conv2d_backward, "2d convolution backward");
}

I test extensions like this:
import torch
import torch.nn.functional as F
from torch.autograd import Function
import math
import cudnn_conv2d
from torch.utils.cpp_extension import load

cudnn_convolution = load(name="cudnn_convolution", sources=["cudnn_convolution.cpp"], verbose=True)

input  = torch.zeros(1, 1, 4, 4).to('cuda')
weight = torch.zeros(1, 1, 3, 3).to('cuda')
bias   = torch.zeros(1).to('cuda')

stride   = (1, 1)
padding  = (0, 0)
dilation = (1, 1)
groups   = 1

# # compute the result of convolution
output = cudnn_convolution.conv2d(input, weight, bias, stride[0], stride[1], padding[0], padding[1], dilation[0], dilation[1], groups, False, False)

grad_output = torch.zeros(1, 1, 2, 2).to('cuda')

grad_i, grad_w = cudnn_convolution.conv2d_backward(input, grad_output, weight, padding[0], padding[1], stride[0], stride[1], dilation[0], dilation[1], groups, False, False, [True, True, False])

print(grad_weight.shape)
print(grad_input.shape)

I receive the following error:

I can not find bug in the code. Does anyboby know how to debug?
