Problem in importing fipy

[amitsoni.1984 at gmail.com]

Hi,

I am using fipy for solving an ODE on python.

I am getting an error in the line: "from fipy.meshes.grid1D import
Grid1D", which says:
ImportError: No module named fipy.meshes.grid1D
Importing only fipy also gives a similar error.

I have Python2.4.4, numpy, matplotlib and fipy installed on my
computer.

Can anyone help me with this?
Is there any other package in Python with which I can solve ODE/PDEs?

Thank you,
Amit
