I am trying to freeze a Python script that contains an import from osgeo but the executable fails with an ImportError: No module named '_gdal'.

I've stripped down my script to just one line:

import osgeo

When running in Python (version 3.3.3) all is well. I've tried freezing with cx_Freeze and py2exe. Both report that there is a missing module: ? _gdal imported from osgeo (among others) but successfully freeze the script. Then the exe fails with the above ImportError.

I've tried importing _gdal in python and it works. I tried manually including the osgeo module in the freezing options but still get the same error.

There is a similar question here: Importing GDAL with cx_Freeze, Python3.4 but maybe this isn't a cx_freeze issue because it also happens with py2exe (it has experimental support for python 3 now).

Does anybody know how to fix this?

  • Same question I asked the last person with this problem: if you do `import _gdal` and then `print(_gdal)` in a Python prompt, what does it show you? – Thomas K Sep 24 '14 at 17:00
  • @ThomasK importing `_gdal` fails unless I import `osgeo` first. After I do that, `print(_gdal)` prints: `` – Harry G. Sep 24 '14 at 22:51
  • Oh, swig is doing funny things. Try going into `C:\Python33\lib\site-packages\osgeo\__init__.py` and editing line 13 (ish) from `import _gdal` to `from . import _gdal`, and then freezing again. Here's the file as I'm suggesting you change it: https://gist.github.com/takluyver/ac036f733c6f79342780 – Thomas K Sep 25 '14 at 01:14

I found a fix. I edited the osgeo\__init__.py file and modified line 13 like this: import osgeo._gdal. This works but only if the module osgeo._gdal is manually included when freezing. @Thomas K Your solution does the same thing I guess.

Note that the same modification must be applied both at osgeo.ogr (line 18) and osgeo.osr (line 18) modules if they are needed (import osgeo._ogr and import osgeo._osr respectively). This means that these must be manually included when freezing as well. My freezing command now looks like this: python cxfreeze.py module1.py --include-modules=osgeo._gdal,osgeo._ogr,osgeo._osr.

Thanks @Thomas K for your help.
