[yt-users] building fKDpy.so manually

[Remudin Mekuria]

Hi all, 

While trying to run the attached script from "yt-cookbook" to get halo mass function, I am getting NameError: global name 'fKD' is not defined. 
It looks like I am tied up already, since I can't do "yt update" on the top of my manual installation. If I am not wrong, it looks to me that I have to  build fKDpy.so, may you help me on how to do that. Thank you in advance for your kindest help.


Cheers,

Remudin
