QgsSpatial Index

I've a very large linear shapefile wich represents pipes. I need to determine the position of every intersection between lines in this shape, only where no vertices already exists (I think with 0,-1 vertices) to create a new punctual layer. I've already tried some methods with lines intersection and validity checker with no luck. In the following image I need to find the point indicated with the blue arrow, not the red circles. The red line (and the pink line intersected) is continuous.

from qgis.core import QgsProject, QgsSpatialIndex, QgsFeatureRequest, QgsRenderContext from qgis.PyQt.QtGui import QColor from collections import Counter trafolar_layer = QgsProject.instance().mapLayersByName('transformator_dagitim')[0] # Trafolar katmanı kesiciler_layer = QgsProject.instance().mapLayersByName('kesici')[0] # Kesiciler katmanı ayirici_layer = QgsProject.instance().mapLayersByName('ayirici')[0] # Ayırıcılar katmanı kesici_index = QgsSpatialIndex(kesiciler_layer.getFeatures())...

Asked today Viewed 7 times I have a successful Python code that runs in the QGIS Python Console when a project is open to calculate the shortest path between hundreds of points. I now want to run the code across lots of projects without actually opening them in the GUI, but still using the QGIS Python Console. My code runs but it fails to calculate the shortest path. Do I need to amend or change the code to ensure it runs without opening the project in the GUI? Below are some key parts of the code.
