No module named - Running script from Terminal/IronPython [duplicate]

When I try to open a scrpit using IronPython, I get an error: No module named 'config'


File structure for python project:



Root



ConfigGenerator



__config_generator.py







config.py




__config_generator.py:
import config

CONFIG = config.Config()

def __main():
# there are redundant to the question code

if __name__ == '__main__':
__main()



And now C# project:
using Microsoft.Scripting.Hosting;
using IronPython.Hosting;
using System;
using System.Windows.Forms;

namespace ProjectName
{
public partial class MainForm : Form
{
private ScriptEngine _engine;

public MainForm()
{
_engine = Python.CreateEngine();

InitializeComponent();
}

private void StartConfigGenerator_Click(object sender, EventArgs e)
{
RunScript(@"Q:\Project\Python\Bots\Root\ConfigGenerator\__config_generator.py");
}

private void RunScript(string path)
{
_engine.ExecuteFile(path);
}
}
}
