import ndlml: No module named 'ndlml'

Hello, I'm trying to run [demGplvmOil1.py](https://github.com/lawrennd/fgplvm/blob/master/python/demGplvmOil1.py), but when I try to import ndlml python tells *No module named 'ndlml'*, if I try **sudo pip install ndlm** it returns "ERROR: No matching distribution found for ndlml". Where should I take tha script or package?
