Flask/Keras webservice ModuleNotFoundError: No module named 'tensorflow_core.keras'

i'm building a simple webservice to classify an image. Separated my keras model classifies correctly and the flask service is running.

But when i try to use the keras model in my flask app ...

from flask import Flask

from myproject.keras_model_wrapper import get_result

APP = Flask(__name__)


@APP.route('/')
def keras_result():
    return get_result()

if __name__ == 'main':
    APP.run()

... an import error occurs.

ModuleNotFoundError: No module named 'tensorflow_core.keras'

I don't know if it's important that the import system searches out of my .venv and TBH I have no idea, what exactly I should search for solving it on my own.

Every hint is welcome

A Workaround that Works perfectly for Flask==1.1.1 and tensorflow==2.1.0

In Flask you should put "import tensorflow as tf" in the "__init__.py" file.

In Django you should put "import tensorflow as tf" in the "manage.py" file.

I don't consider this to be a solution but Setting flask_debug=1(off) will allow you to continue working but you will need to restart the server after every change.

The issue is being tracked in TensorFlow Repo at the link below.
