#2 None nomograph is generated

[Anonymous]

After installing Pynome in Windows 7 Home Premium 64 bits - following strictly the instructions available in "InstallingPyNomoOnWindows"
I tried to compile the BMI example. I got the following result:

IDLE 2.6.6
>>> ================================ RESTART ================================
>>>
Aligning with tag mass
Aligning with tag height
invalid value encountered in double_scalars

Looks like problem in using pyx library. Please run some pyx test files to check installation works.
