about deformable_col2im_gpu_kernel function

[chyueG]

hi,both variables dx and dy range from -2 to 2,can u offer some suggestion why these two variable should change from -2 to 2?

Its a good question, but i forgot how i get over it when i read this function at first. This puzzles me too now. Nevertheless, with the condition on the loop, I think it behaves just like how u expect it.
