[Paraview] Error with python calculator tutorial

[Jonathan Regele]

Hello,

I've searched the web far and wide for an answer to this question, but
can't find it. I'm running Ubuntu 10.04 and want to use the python
calculator. I downloaded the paraview-3.10.1 binary and loaded paraview.
When I follow the tutorial, create sphere assign the expression the
value 5 and apply it gives the following error.

Traceback (most recent call last):
File "<string>", line 4, in <module>
File
"/usr/local/ParaView-3.10.1-Linux-x86_64/lib/paraview-3.10/site-packages/paraview/vtk/dataset_adapter.py", line 5, in <module>
sure that it is installed properly.")
RuntimeError: This module depends on the numpy module. Please makesure
that it is installed properly.


I have python 2.6.5 installed on my computer but my understanding is
that the binary comes with its own set of python. I checked and it looks
like there is python 2.7 in the package directory. It also looks like it
comes with its own version of numpy here

/usr/local/ParaView-3.10.1-Linux-x86_64/lib/paraview-3.10/lib/python2.7/site-packages/numpy/


If I delete the python calculator and try it again I get a different
error message:

Traceback (most recent call last):
File "<string>", line 4, in <module>
File
"/usr/local/ParaView-3.10.1-Linux-x86_64/lib/paraview-3.10/site-packages/paraview/vtk/dataset_adapter.py", line 2, in <module>

import numpy.core.numeric as NX
AttributeError: 'module' object has no attribute 'core'


It gives the same error after that. The error seems to occur when it
tries to import numpy. 

In a linux terminal window, if I open python 2.6 and "import numpy" it
doesn't give me any problems. If I open the python shell in paraview and
try to import numpy I get the following output:

I've tried several things, but it just doesn't make any sense. Any
ideas?
