[Qgis-user] "QgsProcessing" has no attribute 'run' (same for 'processing')

[Johannes Kröger (WhereGroup)]

Hi Zoltan,

the most important thing first: Don't fall into the "AI can program" 
mindset trap. You *will* end up with nonsense like this if you do. Those 
tools can often hallucinate non-existent APIs and mislead you. They 
might work for some more basic or wide-spread code bases but so far I 
have seen very bad results for PyQGIS. Best search the web using 
"pyqgis" as additional keyword to your query.

As https://qgis.org/pyqgis/3.34/core/QgsProcessing.html says, that class 
only contains data to be used by Processing things. It is not your entry 
point into using Processing via Python.

For that please see 
https://docs.qgis.org/3.34/en/docs/user_manual/processing/console.html , 
written by actual, smart humans ;)

And for the Batch file: Don't write your own, QGIS comes with a perfect 
one already, called |python-qgis[-ltr].bat| . See e.g. 
https://gis.stackexchange.com/a/428577/51035

Cheers and good luck!
Hannes
