I am using custom data training using this link. (https://github.com/ravising-h/mmdetection) and getting this error.

mmdet/ops/nms/src/nms_cuda.cpp:9:3: note: in expansion of macro ‘CHECK_CUDA’
CHECK_CUDA(dets);

AT_CHECK is a new API in the high versions of Pytorch. You may use pytorch >= 1.3.

[Qzgfather]

if your pytorch =1.5,You can see pytorch/pytorch#20426, and find AT_CHECK in your code and replace them.I have same problem and i solve it use this way

AT_CHECK is a new API in the high versions of Pytorch. You may use pytorch >= 1.3.

To correct, AT_CHECK is deprecated since PyTorch 1.5, see pytorch/pytorch#36581. You should use higher version MMDetection or use lower version PyTorch.
