原因:在Python3中使用spawn或forkseverver启动方法才支持在进程之间共享CUDA张量。而我是用的multiprocessing是使用fork创建子进程,不被 CUDA 运行时所支持 在程序最开始的地方加上: torch.multiprocessing.set_start_method(‘spawn’)

For debugging consider passing CUDA_LAUNCH_BLOCKING=1. Compile with `TORCH_USE_CUDA_DSA` to enable device-side assertions. Any ideas on what needs to be done to fix this and get it working again? To setup a local environment I use these packages/versions python -m pip install --upgrade ...
After you import cv2 in Python: print(cv2.getBuildInformation()) it should match the opencv_version from earlier. The getBuildInformation will tell you if CUDA is enabled for the OpenCV build you are using in Python. Note that if you’ve been build...
