I uninstalled arcmap and all existing python installations. Then I followed the instructions from https://www.youtube.com/watch?v=Chq9fTRKsHk&t=2s to install qgis and set the environment variables.
I'm attempting to run the script from the second video (https://www.youtube.com/watch?v=Y8JjvBKOCDk&list=PLzHdTn7Pdxs4AvkJeJwlyav2-at9QwKWR) which should launch a blank canvas.
from qgis.core import * from qgis.gui import * from PyQt4.QtCore import * from PyQt4 import QtGui app = QtGui.QApplication QgsApplication.setPrefixPath("C:/OSGeo4W/apps/qgis", True) QgsApplication.initQgis() window = QtGui.QMainWindow() window_frame = QtGui.QFrame(window) 11 window.setCentralWidget(window_frame) frame_layout = QtGui.QGridLayout(window_frame) canvas = QgsMapCanvas() frame_layout.addWidget(canvas) window.show() app.exec_()
It's supposed to bring up a canvas but does not.
The error I'm getting is
Process finished with exit code -1073741819 (0xC0000005)
I don't know if the problem is in the environment variables or in the script. Any ideas?
