Hi, I am using Python.Runtime in C#,
I would like to call 1 function from my script, this function must work in
multip process.
when I call it, it looks like that the sw keep opening new processes forever
till my computer has to be restarted it is like a virus,
my python code:
import math
import multiprocessing
import time
from multiprocessing import pool
import cv2
import numpy as np
import os
from PIL import Image
from GraininessFunction import GraininessFunction
#multiprocessing.set_start_method('spawn', force=True) # or 'fork' on Unix
def getString():
return "Hello from Python!"
def worker(x):
print(f"Processing {x} in PID {os.getpid()}")
return x * x
def multiProcessTest():
multiprocessing.freeze_support()
#multiprocessing.freeze_support()
args = [1,2,3,4]
processes = []
print(f"multiProcessTest in PID {os.getpid()}")
for item in args:
print("creating process for:"+str(item))
p = multiprocessing.Process(target=worker, args=(item,))
p.start()
processes.append(p)
for p in processes:
p.join()
#with multiprocessing.Pool(processes=2) as pool:
#pool.map(worker, args)
#multiprocessing.freeze_support()
#if multiprocessing.get_start_method(allow_none=True) != 'spawn':
#multiprocessing.set_start_method('spawn', force=True)
my C# code:
var ret = module.getString();
Console.WriteLine($"Result from Python: {ret}");
module.multiProcessTest();
Console.WriteLine($"end multiProcessTest");
