This assumed venv sits in your project dir, otherwise you may just need to hard code some paths:

import sys
import os
if sys.executable.lower().endswith("pythonservice.exe"):
    for i in range(4): # goes up 4 directories to project folder
        os.chdir("..")        
    # insert site-packages 2nd in path (behind project folder)
    sys.path.insert(1, os.path.join("venv",'Lib','site-packages'))
