numpy - Can not execute python script or go to python shell

Question

I can not run my Python script or even run command Python to go to python shell. What's wrong with my Python?

machine:project user$ python
Traceback (most recent call last):
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 62, in <module>
    import os

  File "abc.py", line 2, in <module>

    from numpy.lib import add_newdoc

    from .type_check import *

    import numpy.core.numeric as _nx

    from . import numeric
  File "/Library/Python/2.7/site-packages/numpy/core/numeric.py", line 5, in <module>
    import collections
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/collections.py", line 6, in <module>
    __all__ += _abcoll.__all__
AttributeError: 'module' object has no attribute '__all__'

But anyway everything still looks fine if run Python outside my project directory.

You have a local file called abc.py which is hiding the built-in abc module. Rename your file to something else.
