Import error after attempt at importing Class

I attempting to to run a python script inside another python script, upon entering a webpage using Django framework.

This is my views script that is running the python script tech_scripts.py

import subprocess
from django.shortcuts import render

from .models import ConfigInfo
from .forms import ConfigInfoForm

from .models import dhcp
from .forms import dhcpForm

def post_list_three(request):
    from .models import ConfigInfo
    ConfigInfo.objects.all().delete()
    if request.method =="POST":
       form =ConfigInfoForm(request.POST)
       if form.is_valid():
           ConfigInfo=form.save(commit=False)
           ConfigInfo.save()
           subprocess.Popen(["python3", "/home/pi/tutorial/device_interfaces/device_interfaces/tech_scripts.py","-m"])
    else:
        form=ConfigInfoForm()
    return render(request, 'device_interfaces/post_edit.html', {'form':form})

So, upon opening a webpage i want the function post_list_three to be executed. The subprocess manages to run the tech_scripts file which is below

    #!/usr/bin/env python3
import json
import re
import os.path
import pathlib
import uuid
import subprocess

from models.py import ConfigInfo

def info():
    creds=ConfigInfo.objects.first()
    SSID_name=creds.SSID
    psk_name=creds.psk
    sIP=creds.sIP
    netmask=creds.netmask

gateway=creds.gateway
netwrokIP=creds.networkIP
broadcast=creds.broadcast
dns_servers=creds.dns_servers

config['ssid']=getattr(creds,SSID_name)
config['password']=getattr(creds,psk_name)
config['StatIP']=getattr(creds,sIP)
config['Netmask']=getattr(creds,netmask)

config['gateway']=getattr(creds,gateway)
config['Network']=getattr(creds,networkIP)
config['Broadcast']=getattr(creds,broadcast)
config['DNS']=getattr(creds,dns_servers)

jstring = json.dumps(config)
with open("/home/techuser/config.json", "w+") as handle:
    handle.write(jstring)

However, when going to my website after launching it using

 python3 manage.py runserver 192.168.1.150:8000

I get a traceback ,

    [03/Dec/2018 09:51:24] "POST /post/new/static HTTP/1.1" 200 1884

  File "/usr/lib/python3.5/importlib/__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
ImportError: No module named 'mysite'

The traceback highlights that there is something wrong with the line

from models.py import ConfigInfo

Attempts, but failed

from .models import ConfigInfo


import ConfigInfo


from models import ConfigInfo

My models.py below

from django.db import models
from django.conf import settings
from django.utils import timezone

class ConfigInfo(models.Model):
    SSID = models.CharField(max_length=50)
    psk = models.CharField(max_length=50)
    sIP = models.CharField(max_length=20)
    netmask = models.CharField(max_length=20)
    gateway = models.CharField(max_length=20)
    networkIP=models.CharField(max_length=20)
    broadcast=models.CharField(max_length=20)
    dns_nameservers=models.CharField(max_length=20)

How can i fix this issue?
