Unable to use preloaded uWSGI cheaper algorithm - python-3.x

Question

I'm unable to use uWSGI's busyness cheaper algorithm although it appears to be pre-loaded in my installation. Does it still merit an explicit install?
Is so, where can I download the standalone plugin package from?
Any help is appreciated, thank you.

The comments were messing things up for me - the below format fixed the issue
