cuda.pathfinder.find_nvidia_dynamic_lib

cuda.pathfinder.find_nvidia_dynamic_lib(libname: str) → str

Return the absolute path to an NVIDIA dynamic library without loading it.

Resolution is performed by running load_nvidia_dynamic_lib() in a fresh Python subprocess and reporting back the resolved absolute path. The caller’s process does not dlopen / LoadLibrary the library.

Parameters:

libname – Short name of the library (e.g., "cufile", "nvJitLink", "cudart").

Returns:

The absolute path the loader would have used in the caller’s process.

Raises:

• DynamicLibUnknownError – If libname is not a recognized library.

• DynamicLibNotAvailableError – If libname is recognized but not supported on this platform.

• DynamicLibNotFoundError – If the library cannot be located.

Notes

Because resolution happens in a separate process, results may differ from an in-process load_nvidia_dynamic_lib if the caller’s process has DSOs loaded with custom RPATH entries or has already loaded a matching library by some other mechanism. The intent is to report the path the loader would pick when not influenced by other DSOs in the caller.
