python - python run bat file to setup environment variables

问题描述

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

SET ROOT=C:\Program Files (x86)\IntelSWTools\openvino

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"
os.environ["HDDL_INSTALL_DIR"] = "C:\\Program Files (x86)\\IntelSWTools\\openvino\\deployment_tools\\inference_engine\\external\\hddl"
os.environ["ngraph_DIR"] = "C:\\Program Files (x86)\\IntelSWTools\\openvino\\deployment_tools\\ngraph\\cmake"
os.environ["PYTHONPATH"] = "C:\\Program Files (x86)\\IntelSWTools\\openvino\\deployment_tools\\open_model_zoo\\tools\\accuracy_checker;C:\\Program Files (x86)\\IntelSWTools\\openvino\\python\\python3.7;C:\\Program Files (x86)\\IntelSWTools\\openvino\\python\\python3;C:\\Program Files (x86)\\IntelSWTools\\openvino\\deployment_tools\\model_optimizer"

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.
