hi 

I am running a small model to test (Case 16 in qa_test_data/logictree) with very few sources. I get the following error when trying to use full enumeration i.e., "number_of_logic_tree_samples =  0".

ValueError: There are too many potential logic tree paths (759375):raise `max_potential_paths`, use sampling instead of full enumeration, or set use_rates=true

 My input is the same as the original file, only the number of logic tree samples is changed in job.ini.
 
I use 3.21.0. Is there something I can do to allow the engine to run full enumeration?

thanks
Hasib

The error message says to raise max_potential_paths or set use_rates=true. Have you tried one or the other?

Hi Michele

Is that a parameter i should define in the .ini file?
