ImportError: Numeric,numarray or NumPy not found.

This module requires the Numeric/numarray or NumPy module,

which could not be imported. It probably is not installed

(it's not part of the standard Python distribution). See the

Numeric Python site (http://numpy.scipy.org) for information on

downloading source or binaries.

Solution:

When I checked in Python, I had numpy installed, so that wasn’t the issue.

I couldn’t find anything useful online to help me fix it but then I thought, it’s Python and it’s open source. Let’s have a hack!

I opened the following file (if I was more leet I would have used vim or nano or something):

/home/qq/softgrass/python/lib/python2.7/site-packages/wx-2.8-gtk2-unicode/wx/lib/plot.py

I then went to line 117 and added the first three linesshown in the code block below,
remembering to alter all the indents etc:

try:

import numpy as _Numeric

except:

try:

import numpy.oldnumeric as _Numeric

except:

try:

import numarray as _Numeric #if numarray is used it is renamed Numeric

except:

try:

import Numeric as _Numeric

except:

msg= """

raise ImportError, "Numeric,numarray or NumPy not found. \n" + msg

I then saved the file and restarted GRASS and it all (seems) to be running smoothly and as it should do.
