The task which i want to achieve is:

 From scratch, i need numir and mir-algorithm to work on my system 
as a part of one of my repositories.
I need to achieve the following targets as the first go and then 
use mir-algorithm to perform the needful research.

1. Load/save mir.ndslice arrays in NPY format
2. Load/save mir.sparse arrays in coordinate format as NPY files

but i am unable to configure the libraries, have dmd v2.076.1 
installed on my PC.

thanks
