I want to run the idf file in python with eppy package, and the idf file is the one exported from OpenStudio with "Ideal Air Loads On". If I just want to see the load results and don't want to do any details about system, the ideal air load calculation seem to be a good solution. But when I ran the script like "idf1.run()", there're errors like below:

Is eppy run function not compatible with ideal air load calculation? Since the file could run successfully in EP-Launch.
