Solution:
Modify maskscoring_ rcnn/maskrcnn_ benchmark/csrc/cuda/ROIAlign_ Cuda.culine 275:
//Original code: dim3 grid(std::min(THCCeilDiv(output_size, 512L), 4096L));
dim3 grid(std::min(((int)output_size + 512 -1)/512, 4096));
Mask scoring/maskrcnn benchmark/csrc/cuda/ROIAlign cuda.cu3203
//Original code: dim3 grid(std::min(THCCeilDiv(grad.numel(), 512L), 4096L));
dim3 grid(std::min(((int)(grad.numel()) + 512 -1)/512, 4096));
Modify maskscoring_rcnn/maskrcnn_benchmark/csrc/cuda/ROIPool_cuda.cu Line129:
// dim3 grid(std::min(THCCeilDiv(output_size, 512L), 4096L));
dim3 grid(std::min(((int)output_size + 512 -1)/512, 4096));
Modify maskscoring_rcnn/maskrcnn_benchmark/csrc/cuda/ROIPool_cuda.cu line 176:
//dim3 grid(std::min(THCCeilDiv(grad.numel(), 512L), 4096L));
dim3 grid(std::min(((int)(grad.numel()) + 512 -1)/512, 4096));
After modification, execute Python setup.py build development
Error 2:
error: ROIAlign_ Cuda.cu and roipool_ “In cuda.cu file”__ Floorf “and”__ Ceilf “error
error: calling a __host__ function("__floorf") from a __device__
function("get_coordinate_weight<float> ") is not allowed
error: identifier "__floorf" is undefined in device code
error: calling a __host__ function("__ceilf") from a __global__
function("detectron2::RoIAlignRotatedForward<float> ") is not allowed
error: identifier "__ceilf" is undefined in device code
Solution:
Find roialign_ Cuda.cu and roipool_ Cuda.cu file, add F after ceil and floor , that is, ceil is changed to ceilf , floor is changed to floor
the successful implementation is as follows:
