説明

Hey!

I try to make vision with CUDA but I get error during make procedure: My cuda compilation tools: realease 10.0, V10.0.130

Make error output: [ 25%] Building CUDA object CMakeFiles/torchvision.dir/torchvision/csrc/cuda/ROIAlign_cuda.cu.o CMakeFiles/torchvision.dir/build.make:296: recipe for target 'CMakeFiles/torchvision.dir/torchvision/csrc/cuda/PSROIPool_cuda.cu.o' failed make[2]: *** [CMakeFiles/torchvision.dir/torchvision/csrc/cuda/PSROIPool_cuda.cu.o] Error 1 make[2]: *** Waiting for unfinished jobs.... nvcc fatal : Unknown option 'Wall' nvcc fatal : Unknown option 'Wall' nvcc fatal : Unknown option 'Wall' CMakeFiles/torchvision.dir/build.make:270: recipe for target 'CMakeFiles/torchvision.dir/torchvision/csrc/cuda/DeformConv_cuda.cu.o' failed make[2]: *** [CMakeFiles/torchvision.dir/torchvision/csrc/cuda/DeformConv_cuda.cu.o] Error 1 CMakeFiles/torchvision.dir/build.make:322: recipe for target 'CMakeFiles/torchvision.dir/torchvision/csrc/cuda/ROIPool_cuda.cu.o' failed make[2]: *** [CMakeFiles/torchvision.dir/torchvision/csrc/cuda/ROIPool_cuda.cu.o] Error 1 CMakeFiles/torchvision.dir/build.make:335: recipe for target 'CMakeFiles/torchvision.dir/torchvision/csrc/cuda/nms_cuda.cu.o' failed make[2]: *** [CMakeFiles/torchvision.dir/torchvision/csrc/cuda/nms_cuda.cu.o] Error 1 nvcc fatal : Unknown option 'Wall' CMakeFiles/torchvision.dir/build.make:283: recipe for target 'CMakeFiles/torchvision.dir/torchvision/csrc/cuda/PSROIAlign_cuda.cu.o' failed make[2]: *** [CMakeFiles/torchvision.dir/torchvision/csrc/cuda/PSROIAlign_cuda.cu.o] Error 1 nvcc fatal : Unknown option 'Wall' CMakeFiles/torchvision.dir/build.make:309: recipe for target 'CMakeFiles/torchvision.dir/torchvision/csrc/cuda/ROIAlign_cuda.cu.o' failed make[2]: *** [CMakeFiles/torchvision.dir/torchvision/csrc/cuda/ROIAlign_cuda.cu.o] Error 1 CMakeFiles/Makefile2:75: recipe for target 'CMakeFiles/torchvision.dir/all' failed make[1]: *** [CMakeFiles/torchvision.dir/all] Error 2 Makefile:129: recipe for target 'all' failed make: *** [all] Error 2

P.S. I was able to fix this error after remove "-Wall -Wextra -Wno-unused-parameter -Wno-missing-field-initializers -Wno-write-strings -Wno-unknown-pragmas -Wno-missing-braces -fopenmp" params in flags.make

調査方針
The error occurs because nvcc does not recognize the Wall flag, which is passed to it via CMake's flags.make. The user's workaround is to remove gcc specific flags like Wall, Wextra, etc. from the build configuration. To properly fix this, investigate the CMakeLists.txt or the cmake/ directory to see how flags are set for CUDA files. One approach is to use CMAKE CUDA FLAGS or target compile options with proper generator expressions to exclude these flags when compiling .cu files. Also check the existing comments in the issue for any proposed solutions or maintainer responses. Since the issue is from 2020, verify if it has been resolved in later versions.
