Hello!
I want to import your Light-Head RCNN code. Then i have tried to build PSROIAlign but some trouble has occured.
when trying to make:
[ 10%] Building NVCC (Device) object CMakeFiles/cuda_compile.dir/cuda_compile_generated_rotated_ps_roi_align_grad_op.cu.o
.....
[100%] Linking CXX shared library libps_roi_align.so
Error running link command: No such file or directory
CMakeFiles/ps_roi_align.dir/build.make:236: recipe for target 'libps_roi_align.so' failed
make[2]: *** [libps_roi_align.so] Error 2
make[2]: *** Deleting file 'libps_roi_align.so'

make[1]: *** [CMakeFiles/ps_roi_align.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2
I tried using python2 and tensorflow 1.8. How can I solve this problem?
I wrote a custom op, and use gcc cmd to build it, it worked well. Then I try to rewirte the build script with cmake, and use your CMakeLists.txt as example, but when calling the op, it gives the undefined symbol error. It seems the op is skipped by the cmake. The following is gcc script and cmakelists. could you give some advice?
gcc script
