❓ Questions and Help

General questions about detectron2.

Hi, when train models with detectron2, the encountered error is shown below:

RuntimeError: Not compiled with GPU support (ROIAlign_forward at /mnt/lustre/liang1/project/detectron2/detectron2/layers/csrc/ROIAlign/ROIAlign.h:71)

I have install detectron2 with python setup.py build develop, will it compile only with CPU by default? thx.

i run python3 -c ‘import torch; from torch.utils.cpp_extension import CUDA_HOME; print(torch.cuda.is_available(), CUDA_HOME)’, it return True。 and i run detectron2, it still return “RuntimeError: Not compiled with GPU support”, Have you solved it? @ppwwyyxx
