I have a tensorflow model running via a flask server, I was trying to deploy it to the heroku, but it won't let me because the slug size is too large, I'm using the below packages to run the app

Flask,Pillow,Flask-cors,Numpy,Tensorflow

Please reccomend any other free service, or how do I fix this problem in heroku
