nvrtc_120_0.dl在哪里？

Question

我运行了“pip install pycuda来运行cuda文档中的saxy示例，但是运行代码时找不到nvrtc_120_0.dll。显然不是pip下载的一部分。我在哪里可以找到它？

Traceback (most recent call last):
  File "cuda\\_cuda\\cnvrtc.pyx", line 45, in cuda._cuda.cnvrtc.cuPythonInit
pywintypes.error: (126, 'LoadLibraryEx', 'The specified module could not be found.')

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Users\gtwpr\source\repos\PyExt3\PyExt3\PyExt3.py", line 150, in <module>
    err, prog = nvrtc.nvrtcCreateProgram(str.encode(saxpy), b"saxpy.cu", 0, [], [])
