[Qgis-user] polygonize tool gdal error

[Damion Theobald]

When we install QGIS 2.14 or 2.18 on our lab machinesrunning Windows 7 using our software distribution system, everything works fineexcept the polygonize tool. When we install QGIS on standalone machines thistool tends to work fine in most (but not all) cases, occasionally we get thesame problem. I’m struggling to find the cause of this.

 

To reproduce:

 

1) Load a raster file.

2) Raster->Conversion->polygonize. Choose the inputraster and somewhere to write the output vector file and select 'DN'.

 

Error:

 

Traceback(most recent call last): 
File "c:\Programs\QGIS\bin\gdal_polygonize.py", line 35, in 
from osgeo import gdal 
File"c:\Programs\QGIS\apps\Python27\lib\site-packages\osgeo\__init__.py",line 21, in 
_gdal = swig_import_helper() 
File"c:\Programs\QGIS\apps\Python27\lib\site-packages\osgeo\__init__.py",line 17, in swig_import_helper 
_mod = imp.load_module('_gdal', fp, pathname, description) 
ImportError: DLL load failed: The operating system cannot run %1. 

 

 

Any suggestions gratefully received.
