I assume that you have followed getting started document on Heroku and you have a local repository which corresponds to one Heroku app. According to your directory structure you miss Procfile in the root of your project. Create a file called Procfile and add it to your heroku app:

in your project dir:

echo "web: python RunFlask.py" > Procfile
git add Procfile
git commit -m "adding ProcFile"
git push heroku master
heroku ps:scale web=1
heroku open
