Environment
- Pythonnet version: 2.3.0 py35
- Python version: 3.5.4
- Operating System: Windows 10
Details
I want to run this code on my Unity project:
using Python.Runtime;
using UnityEngine;
public class TestLib : MonoBehaviour
{
// Use this for initialization
private void Start()
{
print("initializing python");
PythonEngine.Initialize();
print("running python code");
using (Py.GIL())
{
dynamic np = Py.Import("numpy");
print(np.cos(np.pi * 2));
}
print("Destroying python engine");
PythonEngine.Shutdown();
}
}Here's the output:
It's able to run once but when I try to run it again, Unity editor crashes.
Here's the entire process:
I open Unity. Inside it, I click play to run this code, it works. And then I stop, and then I run the code again, Unity crashes.
Reasoning
- I'm suspecting that it's because python is still running in the background when I stop the game session.
But I tried Initialize() and Shutdown() twice in the code and it works (if I run it once). So I think it's not shutting down issue. It's something else that I cannot figure out. - This error depends on the python code for sure. If I remove the python part and run, it would be able to run as many times as I want.
- It might also be a threading issue which I don't understand.
What are the possible causes and fixes?
