nvcc exited with code 1

Hi Sebastian, Now I have successfully run cmake. However, when I use VS2022 to open the solution file generated by cmake and build the Renderer project, I find there are 4 similar errors as show in the end. It seems my nvcc fails to compile due to some reason. Do you have any clue? One strange thing I notice is that the commend uses cuda v11.7, but actually my NVCC_INCLUDE_DIR is set for v11.6. I used to use 11.7 in my windows PC, but I have just switch to v11.6 to be compatible with pytorch 1.12.1. Thanks a lot!

(below is one of the error, all four errors are similar but for different files) Error MSB3721 The command ""C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.7\bin\nvcc.exe" -gencode=arch=compute_61,code=\"sm_61,compute_61\" -gencode=arch=compute_61,code=\"sm_61,compute_61\" -gencode=arch=compute_61,code=\"compute_61,compute_61\" -gencode=arch=compute_61,code=\"sm_61,compute_61\" -gencode=arch=compute_72,code=\"compute_72,compute_72\" -gencode=arch=compute_72,code=\"sm_72,compute_72\" -gencode=arch=compute_61,code=\"sm_61,compute_61\" --use-local-env -ccbin "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.32.31326\bin\HostX64\x64" -x cu -IC:\Users\Administrator\Documents\GitHub\DiffDVR\renderer -IC:\ProgramData\Anaconda3\envs\diffDVR\include -IC:\Users\Administrator\Desktop\OpenGL\includes\glm -I"C:\ProgramData\Anaconda3\envs\diffDVR\Lib\site-packages\torch\include" -I"C:\ProgramData\Anaconda3\envs\diffDVR\Lib\site-packages\torch\include\torch\csrc\api\include" -I"C:\Users\Administrator\Documents\GitHub\DiffDVR\third-party\cuMat" -I"C:\Users\Administrator\Documents\GitHub\DiffDVR\third-party\magic_enum\include" -I"C:\Users\Administrator\Documents\GitHub\DiffDVR\third-party\cudad\include\cudAD" -I"C:\Users\Administrator\Documents\GitHub\DiffDVR\third-party\tinyformat" -I"C:\Users\Administrator\Documents\GitHub\DiffDVR\third-party\lz4\lib" -I"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.7\include" -I"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.7\include" --keep-dir x64\Debug -use_fast_math -maxrregcount=0 --machine 64 --compile -cudart static -std=c++17 --generate-line-info --expt-relaxed-constexpr --extended-lambda –Xptxas -v -Xcudafe --diag_suppress=cc_clobber_ignored,--diag_suppress=integer_sign_change,--diag_suppress=useless_using_declaration,--diag_suppress=set_but_not_used,--diag_suppress=field_without_dll_interface,--diag_suppress=base_class_has_different_dll_interface,--diag_suppress=dll_interface_conflict_none_assumed,--diag_suppress=dll_interface_conflict_dllexport_assumed,--diag_suppress=implicit_return_from_non_void_function,--diag_suppress=unsigned_compare_with_zero,--diag_suppress=declared_but_not_referenced,--diag_suppress=bad_friend_decl --Werror cross-execution-space-call --no-host-device-move-forward --expt-relaxed-constexpr --expt-extended-lambda -std=c++17 --generate-line-info --expt-relaxed-constexpr --extended-lambda –Xptxas -v -std=c++17 -Xcompiler="/EHsc -Zi -Ob0" -g -D_WINDOWS -DONNX_NAMESPACE=onnx_c2 -D"RENDERER_SHADER_DIRS={\"C:/Users/Administrator/Documents/GitHub/DiffDVR/renderer\",\"C:/Users/Administrator/Documents/GitHub/DiffDVR/third-party/cudad/include/cudAD\",}" -DRENDERER_RUNTIME_COMPILATION=1 -D"NVCC_ARGS=\"arch=compute_61,code=sm_61\"" -D"NVCC_INCLUDE_DIR=C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.6/include" -DRENDERER_BUILD_CPU_KERNELS=1 -DUSE_DOUBLE_PRECISION=0 -DNOMINMAX -DCUMAT_SINGLE_THREAD_CONTEXT=1 -DTHRUST_IGNORE_CUB_VERSION_CHECK=1 -D"CMAKE_INTDIR=\"Debug\"" -D_MBCS -DWIN32 -D_WINDOWS -D"RENDERER_SHADER_DIRS={\"C:/Users/Administrator/Documents/GitHub/DiffDVR/renderer\",\"C:/Users/Administrator/Documents/GitHub/DiffDVR/third-party/cudad/include/cudAD\",}" -DRENDERER_RUNTIME_COMPILATION=1 -D"NVCC_ARGS=\"arch=compute_61,code=sm_61\"" -D"NVCC_INCLUDE_DIR=C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.6/include" -DRENDERER_BUILD_CPU_KERNELS=1 -DUSE_DOUBLE_PRECISION=0 -DNOMINMAX -DCUMAT_SINGLE_THREAD_CONTEXT=1 -DTHRUST_IGNORE_CUB_VERSION_CHECK=1 -D"CMAKE_INTDIR=\"Debug\"" -Xcompiler "/EHsc /W1 /nologo /Od /FdC:\Users\Administrator\Documents\GitHub\DiffDVR\build\renderer\Debug\Renderer.pdb /FS /Zi /RTC1 /MDd /GR" -o Renderer.dir\Debug\renderer_cuda_impl.obj "C:\Users\Administrator\Documents\GitHub\DiffDVR\renderer\renderer_cuda_impl.cu"" exited with code 1.

One possible cause might be the mismatch in the CUDA versions. That is a common issue on Windows with CMake and multiple CUDA installations. The CUDA version that Visual Studio selects is determined by the toolkit, not by the version found by find_package(CUDA) or similar. Delete the CMakeCache.txt and re-run cmake with cmake -T cuda=11.6 .. from the build-folder. See also https://cmake.org/cmake/help/latest/variable/CMAKE_GENERATOR_TOOLSET.html#variable:CMAKE_GENERATOR_TOOLSET

Hi Sebastian, Thanks for your patient reply. Now it seems every version related to cuda in the output of cmake become 11.6. However, now I encounter an error I have not meet ever before (the output is attached at the end). Does that means I need to manually set some path? currently I just set: set(GLM_INCLUDE_DIR "C:/Users/Administrator/Desktop/OpenGL/includes/glm") set(GLEW_INCLUDE_DIR "C:/Users/Administrator/Desktop/volumeGL/includes/gl") set(GLEW_SHARED_LIBRARY_RELEASE "C:/Windows/System32/glew32.dll") set(GLFW_INCLUDE_DIR "C:/Users/Administrator/Desktop/OpenGL/includes/GLFW") set(GLFW_LIBRARY "C:/Users/Administrator/Desktop/OpenGL/lib/glfw3.lib")

Could not find a package configuration file provided by "Torch" with any of the following names:

TorchConfig.cmake
torch-config.cmake

Add the installation prefix of "Torch" to CMAKE_PREFIX_PATH or set "Torch_DIR" to a directory containing one of the above files. If "Torch" provides a separate development package or SDK, be sure it has been installed.

-- Configuring incomplete, errors occurred! See also "C:/Users/Administrator/Documents/GitHub/DiffDVR/build/CMakeFiles/CMakeOutput.log".

If you look at the path to Python in the first log and the second log you sent me, you notice that in the first log, the path was set to python executable in the diffDVR environment, in the second one it was set to the global python installation. Did you forget to activate the diffDVR anaconda environment before launching CMake anew with a clear CMakeCache and the correct cuda toolkit?

Hi Sebastian, Sorry for the stupid mistake I just made. Yes, I forget to activate diffDVR. Not I successfully pass the cmake, but the build error for Render persists. Do you have any other clue or solutions?

Another clue is that when I try to build Renderer-kernels, I find there are also many errors and warnings of the same type: for example:

Warning MSB8065 Custom build for item "C:\Users\Administrator\Documents\GitHub\DiffDVR\build\CMakeFiles\7db998e53d2b8c190076e8be28ffedc4\cooperative_groups.cuh.cpp.rule" succeeded, but specified output "c:\users\administrator\documents\github\diffdvr\build__cmrc_renderer-kernels\intermediate\renderer\cooperative_groups.cuh.cpp" has not been created. This may cause incremental build to work incorrectly. Renderer-kernels C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VC\v170\Microsoft.CppCommon.targets 245

Error C1083 Cannot open source file: 'C:\Users\Administrator\Documents\GitHub\DiffDVR\build__cmrc_Renderer-kernels\intermediate\renderer\cooperative_groups.cuh.cpp': No such file or directory Renderer-kernels C:\Users\Administrator\Documents\GitHub\DiffDVR\build\c1xx 1

Ok, so we are now in the realm of speculation. I'm on the move at the moment and can't try out the code myself. Let's see

The error that the file cooperative_groups.cuh.cpp indicates, that the CMRC resource generator did not run successfully. This is strange, because that is a stage in the cmake configuration step, not in the actual build process. But cmake did run and finish, didn't it? Can you check if you see messages about generating resource files? Can you check if those cmrc-folders exist and contain the missing .cpp files? For context: For runtime compilation, the source files of the kernels have to be available in the executable. CMRC is a CMake resource compiler that creates .cpp files with a big, static char array that encodes the resources.

Another possible avenue would be to remove setting RENDERER_SHADER_DIRS via add_definitions in CMake. This can sometimes give problems with escaping of the special characters in there. Instead, hardcode the content of this variable (you see it in the compiler log) in kernel_loader.cpp, where it is used to enumerate the source directories.

Hi Sebastian, I just delete everything inside the build folder and re-run "cmake -T cuda=11.6 .." to check. Yes, cmake did run and finish (the output is attached in Appendix). As for CMRC resources, I see "# resources file(DOWNLOAD "https://raw.githubusercontent.com/vector-of-bool/cmrc/master/CMakeRC.cmake" "${CMAKE_BINARY_DIR}/CMakeRC.cmake")" in the top level cmake file, but the CMakeRC.cmake file is empty after the build is done. And I see the folder "C:\Users\Administrator\Documents\GitHub\DiffDVR\build__cmrc_Renderer-kernels\intermediate\renderer" exists but is empty. I think that's the problem. And I find in the top-level cmake file the option RENDERER_SHARED_LIB is set to off by default, I don't know what it is for and if it is relevant.

For the other possible avenue you mentioned, I cannot find where in cmake file we set RENDERER_SHADER_DIRS via add_definitions. Could you provide me with more clue on that if possible?

Hi Sebastian, I managed to compile without GUI on a linux docker image (deployed on a commertial cloud server actually), the environment is "Python3.7, CUDA 11.1, cuDNN 8.0.5, Pytorch 1.8.1, Horovod 0.22.1, Ubuntu 18.04, VNC, NVCC11.1, OpenMPI 4.0.0", and I successfully run "/tests/camera/run_entropy2d.py " (during this process I meet exactly the same problems as #2 , a lot of time is saved thanks to your discussion) . However, I can only succesfully run two example volume data (tooth1.json and plume100-linear.json). I have to commend out the example for single_jet.json and c60multi-pw.json because if I don't, I will encounter the error below:

convert relative path to absolute path, load /DiffDVR/pytests/volumes/cvol/C60Large.cvol Traceback (most recent call last): File "./tests/camera/run_entropy2d.py", line 718, in run("./config-files/c60multi-pw.json", "C60multi", "export", False, hemisphere="small") File "./tests/camera/run_entropy2d.py", line 711, in run data = compute(settings_file, name, include_color_in_entropy, save=False, params=params) File "./tests/camera/run_entropy2d.py", line 41, in compute volume = s.load_dataset() File "/DiffDVR/pytests/diffdvr/settings.py", line 58, in load_dataset return pyrenderer.Volume(path) RuntimeError: Illegal magic number

Hi, related to the "Illegal magic number" error, this occurs when the path to the file is wrong, i.e. a file-not-found error. The log says that the volume is loaded from /DiffDVR/pytests/volumes/cvol/C60Large.cvol (absolute path!). The file, however, is available in the repository under pytests/volume/C60Large.cvol. This should be fixed now

Related to RENDERER_SHADER_DIRS, it is set here in the CMake file: https://github.com/shamanDevel/DiffDVR/blob/master/renderer/CMakeLists.txt#L164 And used here https://github.com/shamanDevel/DiffDVR/blob/master/renderer/kernel_loader.cpp#L143 in the source file.

So on windows, can you try removing that line in CMake and hard-code the path in kernel_loader.cpp as following (replaces line 141ff):

int index=0; //this is still the old code
static const char* RENDERER_SHADER_DIRS[] = {"C:/Users/Administrator/Documents/GitHub/DiffDVR/renderer","C:/Users/Administrator/Documents/GitHub/DiffDVR/third-party/cudad/include/cudAD"};
for (const char* rootStr : RENDERER_SHADER_DIRS) { 
 //...

and removing the #ifdef guards for the preprocessor makro.

Hi Sebastian,

 //...
and removing the #ifdef guards for the preprocessor makro.

Your instuction above is correct! Now the CMakeRC file is not empty, and so does the folder "C:\Users\Administrator\Documents\GitHub\DiffDVR\build__cmrc_Renderer-kernels\intermediate\renderer", I can now successfully build the Renderer_kernals project. However, when I try to build the Renderer projects, the four errors persists as below (I just show one of them since all four are simialr)

Hi Sebastian, I decide to first use the linux version to learn and utilize your code, and come back to the windows version later after I understand your code better. If I manage to solve it, I will post the solution here (if it is not a too specific or stupid problem :)

Hi, sounds good. Sorry that I couldn't help you further with the Windows version
