These two days, run a mask RCNN series of network code, and execute the command Python 3 setup A bunch of such errors are received during py build development, as follows:

11 errors detected in the compilation of ".../detectron2/layers/csrc/deformable/deform_conv _cuda.cu".

Solution:

Replace all AT_CHECK in deform_conv_cuda.cpp with TORCH_CHECK

or macro definition:

#ifndef AT_CHECK
#define AT_CHECK TORCH_CHECK 
#endif
