How do I 'force' python to use a specific version of a module?

I'm new to python so I apologize if this has been answered elsewhere with tags I haven't thought of.

I'm trying to update numpy from the 1.6 version I have now to 1.8. I've installed numpy in my python site-packages when I call numpy it calls the old 1.6 version. I've tried looking for the root to numpy 1.6 so I can remove it but that leads to :-

import numpy
print numpy.__version__
print numpy.__file__
>>>
1.6.2
V:\Brian.140\Python.2.7.3\lib\site-packages\numpy\__init__.pyc

I've added the folder containing the module to the system path using:-

sys.path.append('C:/Python27/Lib/site-packages')

and I know this works as I can call other modules in this location with no errors, for example:-

import wx
import Bio

and

import nose

produce no errors. Why is this happening and how can I tell python which version of numpy to use?

Solution

  • This is a very messy solution and probably shouldn't be encouraged but I found that if I remove the location of the old version of numpy from the system path I can call the version I want. The specific lines were:-

    import sys
sys.path.append('C:/Python27/Lib/site-packages')
sys.path.remove('V:\\\Brian.140\\\Python.2.7.3\\\Lib\\\site-packages')
import numpy
