python numpy ImportError: No module named core

Question

Im unable to launch a python script using numpy - any idea what/where this core is?

Traceback (most recent call last):
  File "/scripts/python/foo.py", line 9, in <module>
    import numpy
  File "/packages/python/2.7.2/lib/python2.7/site-packages/numpy/__init__.py", line 156, in <module>
    import ma
  File "/packages/python/2.7.2/lib/python2.7/site-packages/numpy/ma/__init__.py", line 44, in <module>
    import core
ImportError: No module named core

You are using a very old numpy version (older than 1.7, which was released 4+ years ago) that still uses implicit relative imports within the package. The error you're seeing is a common issue with such imports, and has been addressed in more recent NumPy releases. Update NumPy, and this problem should go away.
