I am trying to call idf in python and change the heating and cooling setpoints and then run it through Python. I am using EnergyPlusV22-1-0. I did lots of research and ended up using "eppy". In the following code, I get an error that means eppy is not compatible with my EnergyPlus version, I guess (not sure). Code:

from eppy import modeleditor
from eppy.modeleditor import IDF
import subprocess

idf_path = "D:\\university\\PhD\\PhD-thesis\\Phase-3\\API\\Example.idf"
idf = IDF(idf_path) ***(Here I get the error)***

heating_schedule_name = "YourHeatingScheduleName"
new_heating_schedule_values = [20.0] * 24  # New setpoint values for 24 hours

schedule = idf.getobject("SCHEDULE:COMPACT", heating_schedule_name)

schedule["HourlyValues"] = new_heating_schedule_values

modified_idf_path = "path/to/modified/input.idf"

energyplus_exe = "path/to/EnergyPlus/executable"
idf_weather = "path/to/weather/file"[energyplus_exe, "-r", "-w", idf_weather, modified_idf_path])

Error: make_idd_index() missing 1 required positional argument: 'debug'

Does anyone have any similar experience with compatibility of eppy with EnergyPlus version? Any help is appreciated.

Have you tried loading the IDD file explicitly before loading your IDF? For example:

from eppy import modeleditor
from eppy.modeleditor import IDF

idf_file = IDF(r"C:\\EnergyPlusV22-1-0\\ExampleFiles\\1ZoneUncontrolledAnnualOutputs.idf")

Yes, I tried that, and it give the same error.
