Thread: [Matplotlib-users] How to install matplotlib for python33?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi,

I am trying to install matplotlib on my RedHat Linux 6.5 with Python33.

Unfortunately, 'matplotlib' rpm isn't available for python33. `python-matplotlib` is included only for python2.6 from Red Hat Linux 6.5.

So I try installing the latest module from matplotlib source using 'python easy_install'.

#*scl enable python33 'bash'*
#*easy_install -m matplotlib
*
The install finished fine, but I am still get this error when I tried to import matplotlib. Is there anything else that I need to config?

# scl enable python33 'python'
Python 3.3.2 (default, Mar 20 2014, 20:25:51)
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> import scipy
>>> import matplotlib
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ImportError: No module named 'matplotlib'

Below is the console when I run "easy_install -m matplotlib".
*At the end, it says "Finished processing dependencies for matplotlib". 
Does that mean matplotlib is not really installed yet?*
Do I miss any steps?

Because this distribution was installed --multi-version, before you can
import modules from this package in an application, you will need to
'import pkg_resources' and then use a 'require()' call similar to one of
these examples, in order to select the desired version:

     pkg_resources.require("matplotlib")  # latest installed version
     pkg_resources.require("matplotlib==1.4.3")  # this exact version
     pkg_resources.require("matplotlib>=1.4.3")  # this version or higher
