On Windows and Linux, the CUDA library is installed by the NVIDIA driver package, and is typically found in the standard library path, rather than with the CUDA SDK (which is optional for running CUDA apps). On macOS, the CUDA library is only installed with the CUDA SDK, and might not be in the library path. Returns: version string (Ex: '9.2') or None if CUDA not found. éNZDarwinz libcuda.dylibz!/usr/local/cuda/lib/libcuda.dylibZLinuxz libcuda.soz/usr/lib64/nvidia/libcuda.soz$/usr/lib/x86_64-linux-gnu/libcuda.soZWindowsz nvcuda.dllz%d.%dièé ) ÚplatformÚsystemÚctypesZwindllZcdllZ LoadLibraryÚcuInitZc_uintÚcuDriverGetVersionZc_intZbyrefÚvalue) rrZ lib_filenamesrZdllZlibcudaZ lib_filenamerÚflagsZretrZ version_intr©r ú0lib/python3.7/site-packages/conda/common/cuda.pyÚ cuda_detectsP      r N)r r r r r Úó
