Have you had a look at the Heroku docs regarding camera interfaces? There is an add-on CameraTag Heroku Cameratag [LINK] Also you might find self-hosting your flask app on an apache2 server a more successful solution. There are many tutorials and the process is not difficult. Heroku is great, but with my experience with face_recognition specifically, if you don't pay for upgrades you will run into issues exceeding memory <550mb. This link here is a great tutorial for self-hosting flask app. Deploy Flask to Apache Server [this video] Furthermore, it may be that Heroku cannot access the local camera peripheral or the device is no longer [0] # Using OpenCV to capture from device 0. self.stream = Web

I've been hacking away at this for a couple weeks now. I got mod_wsgi working using these instructions [LINK] and and this YouTube video [this video] . When I used what I had learned to put my own application into play on my web-server, I had some problems but worked through most of them. The "stopper" was that I had written my application for Python 3.6 and the imports caused errors because mod_wsgi was trying to run them with Python 2.7. Further study made me aware that I needed to install libapache2-mod-wsgi-py3 instead of libapache2-mod-wsgi . At least, that's what I thought from what I read here [LINK] . Now, I have a new error: ubuntu@ip-172-26-13-175:~$ sudo systemctl start apache2 Job for

If you're serious about deploying your webapp to the vast realm of the internet, you will need to use a viable framework to do so. Something like apache should do the job. I won't go into detail as to how to deploy a webapp as there are many tutorials out there, but I'll provide some resources below: [LINK] [LINK] [this video] [LINK] Also remember to activate your SSL/TLS certificate (easy way to do that would be for example certbot) and enable HSTS.
