[gdal-dev] Google Summer of Code

Mon Mar 14 09:11:43 PDT 2016

Hello Dmitry,
I was reading up on the gdalautotest wiki(
http://trac.osgeo.org/gdal/wiki/TestingNotes), and it says, "After building
with either the old or new generation python bindings, and installing them
(or adding them to your path from the build tree)..."

I could not understand what that means. I guess this is important because
when I tried the commands given on that page, I got the following error :

File "./run_all.py", line 37, in <module>
import gdaltest
File"pymod/gdaltest.py", line 37, in <module>
from osgeo import gdal
ImportError: No module named osgeo

Now, as far as I could understand, it is importing a file called "gdal.py"
from a folder called osgeo. I searched for it, and got its path as
"gdal/swig/python/osgeo, whereas the autotest folder is separate.
So my guess is I have to somehow specify the path of "gdal.py"

Could you or anyone please guide me on how to proceed with this?

Thanks
Tanuj
