作者您好，你的工作十分出色，但是我再使用的时候出现了运行时错误，RuntimeError: Not implemented on the CPU，目前不知道怎么解决，请问直接安装后还要进行别的操作吗？

哥们，这不是说的很明显了：RuntimeError: Not implemented on the CPU gpt翻译一下都不至于来问

兄弟，我虽然菜但不至于不知道这个报错的原因，当时这个debug到后面还是解决不了

[BUG423]

您好，我已经收到您的来信，非常感谢！祝好！

[BUG423]

把你的tensor和model都移到同一个gpu设备上就行了，比如： if name == 'main':     # 预先创建 layer 并将其放在循环外部，避免每次循环重新创建     layer = DCNv4(channels=16, kernel_size=3, stride=1, pad=1, dilation=1, group=1).to("cuda:1")     tensor = torch.rand(1024, 1, 16).to("cuda:1")  # BLC     #nnd 现在是BLC     for i in range(512):         result = layer(tensor)         print(i, "result.shape:", result.shape)

你好，请问你使用DCNv4的时候遇到过内存越界问题吗 我这个报错很奇怪 RuntimeError: CUDA error: an illegal memory access was encountered CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect. For debugging consider passing CUDA_LAUNCH_BLOCKING=1. Compile with TORCH_USE_CUDA_DSA to enable device-side assertions

我找到问题是出自：dcnv4_col2im_cuda.cuh这个文件

源码里面：int shm_size = sizeof(opmath_t) (G block_multiplier K) 2; if(!check_backward_warpp(d_stride, D)){ shm_size = sizeof(opmath_t) ((G block_multiplier K) 2 + G block_multiplier blockdimX * 3); } cudaFuncSetAttribute(kernel, cudaFuncAttributeMaxDynamicSharedMemorySize, shm_size);

kernel<<<num_blocks, num_threads, shm_size, stream>>>( value, p_offset, grad_output, G, D, Q, kernel_h, kernel_w, stride_h, stride_w, pad_h, pad_w, dilation_h, dilation_w, height_in, width_in, height_out, width_out, offset_scale, remove_center, block_multiplier, grad_im, grad_offset, padded_offset_dim);

cudaError_t err = cudaGetLastError(); if (err != cudaSuccess) { printf("error in dcnv4_im2col_cuda: %s\n", cudaGetErrorString(err)); printf("launch arguments: gridDim=(%d, %d, %d), blockDim=(%d, %d, %d), " "shm_size=%d\n\n", num_blocks.x, num_blocks.y, num_blocks.z, num_threads.x, num_threads.y, num_threads.z, shm_size); AT_ASSERTM(false, "kernel launch error"); } } 我是不知道你们是怎么修改的，我怎么改都爆illegal memory
