Strange problem on system set up on pc

[lefang16]

Dear Dr Cui,

I'm learning this great power system simulation tool. But I have encountered strange problem to declare a system,

import numpy as np
import andes
from andes.utils.paths import list_cases, get_case

case_path = get_case('kundur/kundur_full.xlsx')
ss=andes.run(case_path)

when I perform this code in a windows device, it returns error like this

Is this due to some file access issue, as this code runs with no error on mac devices. Many thanks for your advise.

You can run andes st in terminal or conda prompt to do the selftest and paste the test messages there, then we can better understand what happened.

Thanks for your response. Please see the message below.
