SciPy and NumPy on Mac OS 10.6.8
I have installed Python 2.7.2 on my Mac, and it's working fine. I downloaded the binary for SciPy (http://sourceforge.net/projects/scipy/files/scipy/0.9.0/scipy-0.9.0-py2.7-python.org-macosx10.6.dmg) and NumPy (http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/numpy-1.6.1-py2.7-python.org-macosx10.6.dmg) respectively, and installed them.
However, when I tried the following, error occurred:
>>> import numpy
>>> print numpy._version_
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
print numpy._version_
AttributeError: 'module' object has no attribute '_version_'
However, this works fine:
>>> numpy.version.version
'1.6.1'
Since I am new to Python, I just followed on the instructions here. I wonder what may cause the error above? Thanks.
What you are looking for is numpy.__version__ with two underscores before and after the word version. By my inderstanding, that is the convention for private (or semi-private) variables in python.
