Yeah for sure! Here's some questions - how did you install your libraries and python? Does your Procfile look exactly like this: web: gunicorn app:app? *Note the spacing* and in your case your second "app" might be different from mine if you didnt name your flask file app.py. And in your requirements.txt do you have all the relevant libraries and dependencies? Lastly, does your Aptfile contain those libraries? If all those isnt it, feel free to post what errors you have from terminal so I can help!
