• As i'm working on POC using C# Console Application .I have a requirement on executing multiple "PY.GIL" to handle different tasks using threads . The sample code is able to reach "PY.GIL" initialization after thread call but after that there is no progress the screen got freeze and shows only black screen.

• The below is the sample code used:
  using System;
  using System.Threading;
  using Python.Runtime;
  Class program
  {
  public static void Main(string[] args)
  {
  var virtualpath="Specify the Path";
  Runtime.PythonDLL="Specify the DLL path";
  .///....Set Environment Variables...
  PythonEngine.PythonPath="pythonpath"+"Environment Variables path";
  PythonEngine.PythonHome=virtualpath;
  PythonEngine.Initialize();
  // Creating Threads..
  Thread thread1=new Thread(() => RunCode("Executing From Thread1");
  Thread thread2=new Thread(() => RunCode("Executing From Thread2");

thread1.Start();
thread2.Start();

thread1.join();
thread2.join();
//Shutdown PythonEngine
PythonEnginer.ShutDown();
}
static void RunCode(string threadName)
{
try
{
using(Py.GIL())
{
dynamic math=Py.Import("math");
double sqrtResult=math.sqrt(36);
double powResult=math.pow(2,3);
//print results
Console.WriteLine($"{threadName}: sqrt(25)={sqrtResult}, 2^3={powResult});
Console.ReadLine();
}

}
catch(Exception ex)
{
Console.WriteLine(ex.string());
}
}
}

Additional Details:

1. I'm not getting any errors while reaching "Py.GIL", getting blank screen.

Questions:

How can i execute multiple GIL in parallel to handle python local invocation for different use cases..
I am grateful for any suggestions or insights into resolving this issue.
