setup script not installing the pogs library itself
Thanks for directing me from pogs-python to here.
Using python setup.py install in optkit\python, and in python, using the command, import optkit I get the following error. Looking through the directories, seems like these library files were not installed anywhere and hence cannot be accessed.

issues with arguments fed to solver
Hi,
This looks like a really cool library ! I've been trying to get it up and running but have been having this error when arguments are fed to the solver:
TypeError: long() argument must be a string or a number, not 'ok_function'
I tried with my own examples and also ran some of the test cases e.g. radiation.py. Any advice as to what I'm doing wrong would be greatly appreciated!
I've been using the dev branch as had issues with the master branch as described previously.
Thanks a lot !
The full error for radiation.py below
