face_detection_app

• Streamlit App with OpenCV

How to Deploy on Heroku

• To deploy on heroku you will need the basic 3 requirements and a new requirement for the OpenCV
• This is due to the fact that opencv requires some dependencies that you need to install.

3 Basic Requirements

• Procfile
• setup.sh
• requirements.txt or pipfile

Requirements For OpenCV

• Buildpack

• To check if you have the buildpack installed you can use

heroku run bash
apt --help

• If it shows the help, that means you have the buildpack for apt installed
• If you do not have it you can use this command to install the buildpack

heroku buildpacks:add --index 1 https://github.com/heroku/heroku-buildpack-apt --app your app name

• Aptfile

• You can then include a file called Aptfile which contains the basic dependences/copy and paste into Aptfile

libsm6
libxrender1
libfontconfig1
libice6

• NB: This is the same as installing with apt on a paid account

apt-get install libsm6 libxrender1 libfontconfig1 libice6

Deploying

• Then just like before you run after adding to your repo you can push to heroku to deploy by

git push heroku master

NB: From github connection run half of requirements avoiding timeout. It'll be cached in heroku then the second half
