python run bat file to setup environment variables

Question

i have a.bat file which executes multiple set command to add environment variables, for further scripts to execute,

i tried below code which is not working

import subprocess
subprocess.call([r'C:\Users\User\Desktop\my_vars.bat'])   

below is my bat file

Edit: below script is from opnevino toolkit samples

from __future__ import print_function
import subprocess
import os
#os.system("C:\\Windows\\System32\\cmd.exe /c C:\\Users\\LaserTrac\\Desktop\\my_vars.bat")
#subprocess.call([r'C:\Program Files (x86)\IntelSWTools\openvino\bin\setupvars.bat'])
subprocess.call([r'C:\Users\LaserTrac\Desktop\my_vars.bat'])


#!/usr/bin/env python
  

import sys
import os
from argparse import ArgumentParser, SUPPRESS
import cv2
import numpy as np
import logging as log
from openvino.inference_engine import IECore
import datetime

#log.basicConfig(format="[ %(levelname)s ] %(message)s", level=log.INFO, stream=sys.stdout)
log.info("Loading Inference Engine")
ie = IECore()

# --------------------------- 1. Read IR Generated by ModelOptimizer (.xml and .bin files) ------------
#model_xml = args.model
model_xml = "D:/openvino/2/frozen_inference_graph.xml"
model_bin = os.path.splitext(model_xml)[0] + ".bin"
#log.info("Loading network files:\n\t{}\n\t{}".format(model_xml, model_bin))
net = ie.read_network(model=model_xml, weights=model_bin)
# -----------------------------------------------------------------------------------------------------

as per suggestion in comments i tried setting os.environ as below and checked with print().

import os
#os.system("C:\\Windows\\System32\\cmd.exe /c C:\\Users\\LaserTrac\\Desktop\\my_vars.bat")
#subprocess.call([r'C:\Program Files (x86)\IntelSWTools\openvino\bin\setupvars.bat'])
# subprocess.call([r'C:\Users\LaserTrac\Desktop\sample.bat'])
# import set_vars
os.environ["ROOT"] = "C:\\Program Files (x86)\\IntelSWTools\\openvino"
os.environ["INTEL_OPENVINO_DIR"] = "C:\\Program Files (x86)\\IntelSWTools\\openvino"
os.environ["INTEL_CVSDK_DIR"] = "C:\Program Files (x86)\IntelSWTools\openvino"
os.environ["OpenCV_DIR"] = "C:\\Program Files (x86)\\IntelSWTools\\openvino\\opencv\\cmake"
os.environ["InferenceEngine_DIR"] = "C:\\Program Files (x86)\\IntelSWTools\\openvino\\deployment_tools\\inference_engine\\share"

print(os.environ["PYTHONPATH"])
import from openvino.inference_engine import IECore

print(os.environ["PYTHONPATH"]) prints correct value what i set but error i got is no module named openvino, if i set these variabel from bat file directly in cmd and then execute my py file in same cmd, it works.

problem is i want to set physical path of openvino installation in environment variable so in the next line i can do "import openvino", and os.environ sets environment variable after python.exe process starts, so may be this is not possible, os environ is may be only for data variable type purpose. am i right??

I'm not sure if what you are trying to do is possible. However, there is a guide to setup the OpenVINO environment variables permanently on Windows 10 . This way you don't have to call the setupvars.bat script every time. The guide has a list of the variables needed for OpenVINO and their path.
