I'm new to GIS but I've already a signifiant experience in development. I work on new project. We're trying to use the power of Qgis to create a GIS tool for our commercial team.
QGis is istalled from OSGeo4W (3.8), Python (3.7) and PyQt (from pip) are installed too.
Correctly set PYTHONPATH :
set PYTHONPATH=C:\OSGeo4W64\apps\qgis\python
When i try to run my python script (copied from the official documentation "PyQGIS Developper Cookbook"), we've got an error :
from qgis.core import *
# Supply path to qgis install location
QgsApplication.setPrefixPath("C:\OSGeo4W64\apps\qgis", True)
# Create a reference to the QgsApplication. Setting the
# second argument to False disables the GUI.
qgs = QgsApplication([], False)
# Load providers
qgs.initQgis()
# Write your code here to load some layers, use processing
# algorithms, etc.
# Finally, exitQgis() is called to remove the
# provider and layer registries from memory
qgs.exitQgis()
ImportError: DLL load failed: %1 n’est pas une application Win32 valide.
