I am a new user of Python and need to also use matplotlib but I am having some problems which I hope somebody will be able to help me with.
I have two versions of Python on my laptop that runs on Windows XP. Version 2.4 installed in a folder named python 24 and I also have VisIt which has associated with it Python Version 2.5. I installed matplotlib for version 2.4 on my laptop and it detected the Python version 2.4 and installed itself in the right folder. However I can only use Python 2.4 when I am in this folder (c:\python24). When I call python from any other folder is loads the 2.5 version.
For the other version of Python (the 2.5 version) I can call this version from any
directory but when I installed matplotlib for Python version 2.5, it will not import pylab even though I can call this version of Python from any folder.
The problem I have is I have a working folder with subfolders and I need to use pylab for some plots. If I call python from this folder it loads 2.5, which will not import pylab. I put the working folder in c:\python24\ and it still calls 2.5 version.
How can I get my system to call python 2.4 from any folder
Or
Get python 2.5 to import pylab.
I have put the path for both
versions of python as shown below:
I guess you have specific reason to prefer to use python2.4 and not install matplotlib into python2.5
I also have 2 versions installed on my computer, .. only one will work directly from the command line, the first one found on the path.
however whenever I want to run a test against Version2.4 I can do that by calling the interpretor directly and pass the script name
from command prompt
c:\python24\python myscript.py
or if you want to run the interpretor interactively
D:\>
D:\>c:\python24\python
Python 2.4.3 (#69, Mar 29 2006, 17:35:34) [MSC v.1310 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

D:\>c:\python25\python

Hope this helps

Path to Python version 2.5:
C:\Program Files\LLNL\VisIt 1.6.1\Python\Lib;C:\Program Files\LLNL\VisIt 1.6.1\Python\DLLs;C:\Program Files\LLNL\VisIt 1.6.1\Python\Lib\lib-tk
Path to Python version 2.4:
C:\Python24\Lib;C:\Python24\DLLs;C:\Python24\Lib\lib-tk
Thanks for your help
