I've tried various ways to acccess my *.model3 file using PyQGIS libs as standalone script.
I can access and run my model from script stored inside QGIS.
processing.run('model:my_model_name', params)
Is this even achievable outside of QGIS?
How can I extend algorithms/models list when running standalone scripts?
Should I export my model to python and then follow instructions specified at Using custom Processing algorithm from standalone PyQGIS scripts (outside of GUI) ?
