No ogr module despite having gdal installed?

Question

I am trying to use the mapping component of the wonderful PySAL package, but for some reason I do not have the ogr module. I was under the impression that it came packaged with gdal. Am I missing something?

import gdal
import ogr

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-29-ef9eb3418665> in <module>()
----> 1 import gdal
      2 import ogr

ImportError: No module named gdal

UPDATE: I am afraid I was in a bit of a hurry to catch a plane, so I failed to include some critical information. I already installed python-gdal using the apt-get method described here, because I wanted to leave little to chance. Is it possible that the package manager did not install it correctly?

I am afraid I am not finding osgeo either...

from osgeo import gdal

----> 1 from osgeo import gdal

ImportError: No module named osgeo

Additionally, I should add that I am using Ubuntu 13.04.

Answer 1

Use these commands:

sudo apt-get install python-gdal
sudo apt-get install gdal-bin

Answer 2

Normally the import should look like this:

from osgeo import gdal, ogr

But if you see "ImportError: No module named osgeo", then you didn't install the GDAL Python package correctly. (Hint: if you are using Windows, I strongly recommend this).

Answer 3

I actually just ended up upgrading all of Anaconda when the next iteration was released. I should also note that GDAL was accessible in R, so I am guessing it had something to do with the particular constellation of Python dependencies. Thanks for taking a look.
