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-i686.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

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? -Jeff -- Jeffrey S.

I haven't figured out why yet - perhaps someone on the list who knows more about eggs will chime in. -Jeff -- Jeffrey S.

If it's installed using distutils (instead of setuptools), the basemap stuff just gets written in the matplotlib toolkits directory directly, and everything works fine. I think namespace packages were being used before, but were removed. I don't remember why. Until we get this fixed, I think your symlink trick is the only way to get it to work with python2.3. The warning message appears to be harmless. -Jeff -- Jeffrey S.

We removed the namespace packages support because we were using it improperly. To do it correctly would require moving all of the functionality out of matplotlib/__init__.py. Since there is currently a fair amount of functionality there, adding namespace support would require moving it and breaking the current API. In addition, there are some ongoing issues with performance and namespace packages. Because of this, we had some ambivalence about namespace packages and decided to remove the broken support until we could add proper support, if we decide to go that route. A good time to do that, if indeed we want to, would be when we release Michael's transforms branch, so we can break as much as possible at once. JDH |

This means that python2.3 support would have to be dropped. 2) move the toolkits to basemap_toolkits, as Philip Eby suggested, and make matplotlib_toolkits a namespace package. Unfortunately, this may break lots of existing code. -Jeff -- Jeffrey S.
