I have similar problem on ROS Hydro (Ubuntu 12.04). When I run 'rqt_plot' i get the following error:

ImportError: numpy.core.multiarray failed to import
Traceback (most recent call last):

AttributeError: 'module' object has no attribute 'core'

ROS is configured properly. The solution given by JM didn't work for me. Removing and installing ROS again didn't help. Any ideas what might be possibly wrong?
