Hello,<br>
<br>
I work with Qgis 3.14 in Windows 10<br>
<br>
I try to call a processing algorithm from a python stand alone app,
<br>
I want to run the following script from the custom Networks
algorithm provider but I have the message that the algorithm is not
known<br>
<br>
How to register the provider in the processing registry to be able
to call it?<br>
<br>
<br>
QgsApplication.setPrefixPath("C:/Program Files/QGIS
3.14/apps/qgis", True)<br>
qgs = QgsApplication([], False)<br>
<br>
qgs.initQgis()<br>
import processing<br>
from processing.core.Processing import Processing<br>
Processing.initialize()<br>
<br>
<br>
<br>
processing.run("Networks:musliw_simple_matrix",
{'NODES':'G:/BD_DREAL/2020/script_modele_resmultimodal_light
/noeuds_light_hdf_be.gpkg','NUM':'num','START_POINT':'708675.425564,7063676.157556

<br>
Thanks<br>
<br>
Best regards<br>
