I have been trying to set up my Python web app that uses opencv, tensorflow and av modules but keeps failing. I have tried using the Aptfile to install several Ubuntu libraries (libsm6, libxrender1, etc.) and the install still fails.
After failing the install, the heroku server resolves to building the av module from source which fails as well, with gcc failing here:

Has anyone experienced this? Or any experience with using av/pyav in Heroku? Please tell me anything that I missed. Thanks.
Turns out Heroku works better using requirements.txt than Pipfile. After changing the install file, the deployment process went fine.
