krahenbuhl2013 compatibility issue with Python 3.6.4

[oy321]

Hello,
I have been trying to make this working with Python 3 in a Windows environment. I have fixed most of the issues with the latest eigen code, but got stuck with the DenseCRF map() function in krahenbuhl2013.pyx, where it raised an error message as below:
"...

I was not able to locate this 'moduleobject.c' file in the 'krahenbuhl2013' folder therefore couldn't go further fixing this bug. Any advice would be appreciated.

I understand that I could go for 'virtualenv' and use recommended Python 2.7 setups. But it'd be good to have this library running in Python 3 Windows env as my other code are in this env.

Thank you!

Hi,
it has been a while, but if you are still stuck with this hope this works:

I was able to run this with Python 3.8.0 in WSL with some modification.
Here - https://github.com/rodroadl/intrinsic-python3 - is my code for it

However, one thing I notcied is you ran in Windows environment ( assuming not using WSL), so I don't know how that would play out.
