My flask project structure looks like this:

flask_demo_app

-app

    -__init__.py

    -routes.py

-demoapp_venv

-flask_demo_app.py

My init.py looks like this :

    from flask import Flask



app = Flask(__name__)



from app import routes

code inside flask_demo_app.py

from app import app

code inside routes.py:

    import os

cwd = os.path.abspath(os.path.dirname(__file__))

print(cwd)

from app import app

from flask import render_template

from mySDK_python_sdk.mySDK_core import core_config





@app.route('/')

@app.route('/index')

def index():

    return 'Hello world'





@app.route('/sdk')

def test_sdk1():

    print('invoking from rutes')

    config = core_config.RestClientConfig('194.138.0.25', '9400')

    return config 

mySDK project is my another python project which is installed as a wheel file and available inside demoapp_venv/site-packages. When i run routes.py directly without using flask (of course removing "@app.route"), it invokes the methods inside "core_config" as expected. But when I run flask run command, it gives me module not found error for the modules of the installed "mySDK" project.
I am using pycharm editor and marked the installed packages of mySDK as "source root".

Please let me know why I am getting module not found error for installed app.
