[Python] Why can't I implement ENERGYM?

I am trying to implement the ENERGYM library in Python as per the following paper: https://www.mdpi.com/2076-3417/11/8/3518 and https://bsl546.github.io/energym-pages/sources/install_min.html

After successfully having gone through the path in the second link (minimal installation of energyplus and adding it to the path), I am now able to run the following

import energym


The next step is the following loop:

env = energym.make("Apartments2Grid-v0")
out = env.get_output()
for i in range(100):
forecast = env.get_forecast(forecast_length=10);
inp = get_input(out, forecast);
out = env.step(inp);
kpis = env.get_kpi();
env.close()


However, this gives a long loop of error: starting with about a million lines that look like this:

What might be the issue? ChatGPT is not able to figure it out, and neither am I.
