I am developing a standalone app in Python, using QGIS libraries including processing algorithms. I am developing in Linux environment and I put the libraries in a folder. Also I put the processing folder from QGIS in that same folder. I run the app but when I import the processing folder, it gives me nothing (not even error messages).
I import like that:
Can you help me?
import sys import qgis.core import PyQt4.QtCore import PyQt4.QtGui app = qgis.core.QgsApplication(,True) qgis.core.QgsApplication.setPrefixPath("/usr", True) qgis.core.QgsApplication.initQgis()
(from here the program doesn't work)
from processing.core.Processing import Processing inputLayer = 'c:....' inputMask = 'c:....' extent = .... cellsize = .... outPath = 'c:.....' Processing.Initialize() Processing.runalgorith(.....)
I downloaded the folder with the processing version 2.2.0-2 and I copied to my script folder. I run and it gives me this error:
Traceback (most recent call last): File "teste.py", line 12, in <module> from processing.core.Processing import Processing File "/home/p/Programas/processing/__init__.py", line 28, in <module> from processing.tools.dataobjects import * File "/home/p/Programas/processing/tools/dataobjects.py", line 33, in <module> from processing.core.ProcessingConfig import ProcessingConfig File "/home/p/Programas/processing/core/ProcessingConfig.py", line 30, in <module> from processing.tools.system import * File "/home/p/Programas/processing/core/processing.py", line 33, in <module> from processing import interface ImportError: cannot import name interface
I got it!! What is missing in my case was to define the PYTHONPATH to the folder with the processing. Now I have the correct running of the code.
