[gdal-dev] Help with getting gdal python module working

Candy, Liam

Hi,

 

I’ve managed to get GDAL 2.1.3 to build with ECW 5.3 support on my 64-bit system. The last hurdle I’m struggling with is getting the python module to install and work. The lines in my nmake.opt file relating to python are;

 

!IFNDEF PYDIR
PYDIR = "… \AppData\Local\Programs\Python\Python36”

!ENDIF

 

HAVE_NUMPY=1

 

But the python module does not install.

I’ve tried going into the gdal-2.1.3\swig\python folder and installing manually with “python setup.py install”, but when I try to import gdal in a script with “from osgeo import gdal” I get the error

 

Traceback (most recent call last):

  File "…\AppData\Local\Programs\Python\Python36\lib\site-packages\IPython\core\interactiveshell.py", line 2881, in run_code

    exec(code_obj, self.user_global_ns, self.user_ns)

  File "<ipython-input-3-a04b80bf4e65>", line 1, in <module>

    from osgeo import gdal

  File "D:\Program Files (x86)\JetBrains\PyCharm Community Edition 2016.3.2\helpers\pydev\_pydev_bundle\pydev_import_hook.py", line 21, in do_import

    module = self._system_import(name, *args, **kwargs)

  File "…\Local\Programs\Python\Python36\lib\site-packages\gdal-2.1.3-py3.6-win-amd64.egg\osgeo\__init__.py", line 21, in <module>

    _gdal = swig_import_helper()

  File "…\Local\Programs\Python\Python36\lib\site-packages\gdal-2.1.3-py3.6-win-amd64.egg\osgeo\__init__.py", line 17, in swig_import_helper

    _mod = imp.load_module('_gdal', fp, pathname, description)

  File "…\Local\Programs\Python\Python36\Lib\imp.py", line 242, in load_module

    return load_dynamic(name, filename, file)

  File "…\Local\Programs\Python\Python36\Lib\imp.py", line 342, in load_dynamic

    return _load(spec)

ImportError: DLL load failed: The specified module could not be found.

 

Which I’m assuming is because the GDAL scripts can’t find the relevant GDAL dlls.

 

Any idea on how to fix this ?

 

Best regards,

Liam.
