<div dir="ltr">Hi QGIS users,<div><br></div><div>Good Day!</div><div><br></div><div>Would like to ask how can I execute my python script in Python Shell? It keeps on asking me that the module that I am using does not exist.</div>
<div><br></div><div>I converted the OSGeo4W shell to a python shell using the python command.</div><div>C:\> python</div><div><br></div><div>Then I execute my file >>> execfile('folderpath\\multiband_zonalstat_pythonshell.py')</div>
<div><br></div><div><i>Then it throws an error:</i></div><div><div><i>Traceback (most recent call last):</i></div><div><i> File "<stdin>", line 1, in <module></i></div><div><i> File "folderpath\multiband_zonalstat_pythonshell.py", line 1, in <modul</i></div>
<div><i>e></i></div><div><i> import qgis.analysis</i></div></div><div><br></div><div>This is the script that I am trying to run in python shell:</div><div><br></div><div><div>import qgis.analysis</div><div>vectorlayer = QgsVectorLayer(r"folderpath/YEU.shp", "Ye-U", "ogr")</div>
<div>rasterfile = "rasterpath/cdz_raw_image.img"</div><div>for num in range(1):</div><div><span class="" style="white-space:pre"> </span>zonalstats = qgis.analysis.QgsZonalStatistics(vectorlayer,rasterfile,str(num),num)</div>
<div><span class="" style="white-space:pre"> </span>zonalstats.calculateStatistics(None)</div></div><div><div><br></div><div>I tried checking the system path (please see below), and I think it can locate my OSGeo python installation path.</div>
<div><br></div><div>I also tried editing my system variables path and include the OSGeo python, and OSGeo QGIS path but still it throws the same error.</div><div><br></div><div>I am trying to run my script in a python shell to test if the processing time will be much shorter compare to running it in the python console in QGIS.</div>
<div><br></div><div>On the other hand, I also tried to include the following lines in the beginning of my script with no success:</div><div><div><i>import sys</i></div><div><i>sys.path.extend([r'C:\OSGeo4W\apps\qgis\python', r'C:\OSGeo4W\apps\qgis\bin'])</i></div>
</div><div><br></div><div>it throws this error:</div><div><br></div><div><div><i>Traceback (most recent call last):</i></div><div><i> File "<stdin>", line 1, in <module></i></div><div><i> File "E:\Python_scripts\multiband_zonalstat_pythonshell.py", line 3, in <modul</i></div>
<div><i>e></i></div><div><i> import qgis.analysis</i></div><div><i> File "C:\OSGeo4W\apps\qgis\python\qgis\__init__.py", line 35, in <module></i></div><div><i> from qgis.core import QgsFeature, QgsGeometry</i></div>
<div><i>ImportError: DLL load failed: The specified module could not be found.</i></div></div><div><br></div><div>I am not sure why it can't find qgis.analysis module or is there something wrong with my script.</div>
