How to import .pyx files in Python?

Question

When i run test.py https://github.com/zisianw/FaceBoxes.PyTorch

It imports this file https://github.com/zisianw/FaceBoxes.PyTorch/blob/master/utils/nms_wrapper.py

And this file tries to import the two .pyx files inside this folder

https://github.com/zisianw/FaceBoxes.PyTorch/tree/master/utils/nms

How can I convert those .pyx files to normal Python code or just import them somehow?

I am getting this error without doing anything

from .nms.cpu_nms import cpu_nms, cpu_soft_nms
ModuleNotFoundError: No module named 'utils.nms.cpu_nms'

Possible solution is not working.

import pyximport
pyximport.install()

It is giving me this error

 > ImportError: Building module utils.nms.cpu_nms failed: ["distutils.errors.CompileError: command 'C:\\\\Program Files (x86)\\\\Microsoft Visual Studio\\\\2019\\\\Community\\\\VC\\\\Tools\\\\MSVC\\\\14.25.28610\\\\bin\\\\HostX86\\\\x64\\\\cl.exe' failed with exit status 2\n"]

Does this answer your question? [How do I import function from .pyx file in python?](https://stackoverflow.com/questions/7508803/how-do-i-import-function-from-pyx-file-in-python) — Swetank Poddar, Apr 20 '20 at 20:44
No sir @SwetankPoddar . I mentioned in my question. I get an error, when i try this solution — Rahul, Apr 20 '20 at 20:57
`cl.exe` is the linker that links compiled code into an executable or library. Error 2 *usually* means that a file cannot be found. — Roland Smith, Apr 20 '20 at 21:33
Also, I will later convert this python program to a Pyinstaller exe file. So It would have been perfect, if i could change it to `.py` file. Is it possible? — Rahul, Apr 21 '20 at 06:40
The code inside `.pyx` looks similar to `.py` code with some changes — Rahul, Apr 21 '20 at 06:40
@Rahul you need to install pyximport as follows: `pyximport.install(setup_args={"script_args" : ["--verbose"]})` to see what is going wrong with the compiler options. — Anton K, Sep 06 '20 at 06:03

before import, make sure FaceBoxes and Sim3DR are built successfully, e.g.,

sh build.sh
