Problem with grader requirements

I have a grader that needs additional libraries. They are installed no problem, but when the xqueuewatcher imp loads the grader it doesn't have that library: https://github.com/edx/xqueue-watcher/blob/master/xqueue_watcher/jailedgrader.py#L103

The relevant parts from the grader:

import numpy as np
from numpy import array, matrix
import gradelib
reload(gradelib)
from gradelib import Grader, InvokeStudentFunctionTest, must_define_function, rand, generateRandom2DData

fn = "perceptron"

grader = Grader()
grader.add_input_check(must_define_function(fn))

Should I just make a task in the ansible play to install all the individual coder requirements into the root processes' venv, or is there a better way?

Start with xqueue_watcher/jailedgrader.py around line 103 and trace how the grader is loaded and which environment it uses. Review the grader imports, including numpy and gradelib, then inspect the relevant Ansible play and root process virtual environment setup. Done means the appropriate grader dependencies are available without requiring every coder dependency to be installed globally.
