I moved few steps further I could not resolve the issue above so I moved setup.py in the pylibfreenect2 folder

And changed this code in setup.py

ext_modules = cythonize(
    [Extension(
        name="pylibfreenect2.libfreenect2",
        sources=[
            join("pylibfreenect2", "libfreenect2" + ext),
        ],

to this

ext_modules = cythonize(
    [Extension(
        name="pylibfreenect2.libfreenect2",
        sources=[
            join("libfreenect2" + ext),
        ],

That builds the module and I managed to install it But when I'm running sample it fails on the import. Probably that has to do with the install path but I don't understand how to fix it.

from pylibfreenect2 import Freenect2

I get the error

ImportError: cannot import name 'Freenect2' from 'pylibfreenect2' (unknown location)

I tried a lot of things but cannot resolve the error Probably that has to do with the install path but I don't understand how to fix it.

libfreenect2-0.2.0-usbdk-vs2015-x64 is setup correctly. When I start Protonect.exe it shows images from each Kinect
