Ошибка импорта Ironclad/Numpy, но работает в консоли eclipse

Я пытаюсь использовать numpy с ironpython.

Когда я следую примеру в документации ironclad, запущенной в окне консоли, я получаю эту ошибку.

Однако, если я запускаю тот же пример из консоли IronPython в eclipse, это, кажется, работает.

>>> import numpy
>>> x = numpy.zeros(5)
>>> x

Что eclipse или PyDev делают по-другому, что заставляет это работать?
