I have received the same question, have you found any method to solve it?

I also meet this problem when I try to modify this RCN, and I find that the _dilation is defined in the setup.py file, as:
# Setup C extensions dilation_module = Extension( '_dilation', sources=['science_rcn/dilation/dilation.cc'], )

Actually, dilation.cc is a library in C language written by RCN team, so python cannot import it directly. We have to setup.py it or make it (2 ways to go offered by this project).
so you have two choices,

1. If you wanna directly use RCN, just run the setup.py or 'make' according to the readme before you use this RCN, in order to compile and setup the dilation library.

2. If you wanna badly modify this RCN code, find the corresponding part in setup and change them as you wish to call the dilation.cc library. The related code is here:
   from setuptools import setup, find_packages, Extension
# Setup C extensions
dilation_module = Extension( '_dilation', sources=['science_rcn/dilation/dilation.cc'], )
setup( ext_modules=[dilation_module], )
   then, make the file and nailed it.

But, I still face one problem that I can't debug it step by step as it seems that the _dilation can only be called as a whole.

Helpful.Thank you very much.
