Hi all,

I'm trying to set up matplotlib with basemap on CentOS 4.6
      

with python
    

2.3.4

I installed setuptools 0.6c7, then numpy 1.0.4, then matplotlib 0.91.1_r0, then basemap 0.9.9 (building and installing the GEOS library from source). When I try to run the example simpletest.py script, I get the following message:

/usr/lib/python2.3/site-packages/matplotlib-0.91.1_r0-py2.3-linux-i686
    

.e
gg/pytz/__init__.py:29: UserWarning: Module matplotlib was already imported from

/usr/lib/python2.3/site-packages/matplotlib-0.91.1_r0-py2.3-linux-i686
    

.e
gg/matplotlib/__init__.pyc, but

/usr/lib/python2.3/site-packages/basemap-0.9.9-py2.3-linux-i68
6.egg is
    

being added to sys.path
  from pkg_resources import resource_stream Traceback (most recent call last):
  File "simpletest.py", line 1, in ?
    from matplotlib.toolkits.basemap import Basemap
ImportError: No module named basemap

Any ideas what might have gone wrong? I was expecting basemap to install under /site-packages/matplotlib/toolkits but it installed under a site-package of it's own.

Thanks,
Rich
  

Rich: Unfortunately, I've no idea what's wrong and don't have 2.3 to test on. The install process for 2.3 is a bit different in that it uses setuptools to substitute for features in distutils that didn't appear until python 2.4. Can you easily upgrade to 2.4? If not, can you send a listing of site-packages/matplotlib/toolkits to me, off-list?

Hi Jeff,

Thanks for your response. I might be able to upgrade my prototype
machine to Python 2.4, but I'm not sure about my customer's box.

Here is the listing from
python2.3/site-packages/matplotlib-0.91.1_r0-py2.3-linux-i686.egg/matplo
tlib/toolkits:

__init__.py
__init__.pyc

Regards,
Rich Fought
  

Richard: I've confirmed your problem - in fact, it occurs whenever setuptools is used (and the package is installed as an egg), This happens by default with python2.3, but only if you use setupegg.py for python2.4 and python2.5. I haven't figured out why yet - perhaps someone on the list who knows more about eggs will chime in.

-Jeff
