Installing pycuda on windows

Question

So I try python -m pip install pycuda and it fails (Here's some of the output from the failed install):

Building wheel for pycuda (pyproject.toml) ... error
  error: subprocess-exited-with-error

WARNING: nvcc not in path.

ERROR: Failed building wheel for pycuda
Failed to build pycuda
ERROR: Could not build wheels for pycuda, which is required to install pyproject.toml-based projects

I have installed the Visual Studio 2022 build tools but I have not added anything to my path, which is all I figure I have todo but I don't know what I have to add. The pycuda wiki's installation page specifies

C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64;C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE;

but I don't have those directories. Here's the tree of my visual studio install D:\VisualStudioThings\install\VC. (I cannot include the tree for the whole install because it's too much)

So my question is what do I add to my path?

I can reproduce your issue:

Since you are based on windows, you can try the below steps:

pip install --upgrade pip

pip install --upgrade setuptools wheel

If the above steps still don't make it work on your side, I think the issue should comes from the source doesn't have whl file. Because pip will search package from https://pypi.org/, but in this place, I don't see the package pycuda has whl there.

Based on this, I found whl file of pycuda from other place, download it and install the package via this:

python -m pip install packagefilename.whl

It works well on my side, I can install it at the end:

Where does one get a whl file for pycuda? – kpie Jan 30 '23 at 13:42
@kpie Please refer to this SO question: [How do I install a Python package with a .whl file?](https://stackoverflow.com/questions/27885397/how-do-i-install-a-python-package-with-a-whl-file) – Bowman Zhu-MSFT Jan 31 '23 at 01:43
No I haven't found a pycuda.whl file to try. – kpie Feb 07 '23 at 14:41
@kpie Have you checked the SO question link that I posted before, the whl can be download in [this place](https://i.stack.imgur.com/k8C4K.png). :) – Bowman Zhu-MSFT Feb 08 '23 at 01:57
