I want to create the Voronoi diagram from a set of point (see below). When I use the "Voronoi Polygons" tool from QGIS, there is an error :
File "C:/PROGRA~1/QGIS3~1.0/apps/qgis/./python/plugins\processing\algs\qgis\VoronoiPolygons.py", line 128, in processAlgorithm self.tr('There were no polygons created.')) _core.QgsProcessingException: There were no polygons created.
What do you think is the reason for that?
