In what form are you trying to deploy? I had a lot of trouble getting mine to work as a web app, since I wanted to use free services only. One I put on Zeit v1, though I believe that since they moved to version 2 the approach I used won’t work anymore. The other one I deployed using the Google App Engine, which was also a huge headache. I used GCP to train, and I built a docker image on my GCP instance and then deployed that, but it took multiple attempts before one succeeded and I think I was doing the same thing each time (I’m also super inexperienced when it comes to docker, so others might be able to deal with this better). But then some time later it just randomly stopped working, and I just haven’t gone through the steps again.
Sorry I don’t have anything more helpful to share! But broadly, I’d recommend going through the steps in the ‘production’ sections (e.g. https://course.fast.ai/deployment_google_app_engine.html) and dealing with specific problems as they arise. The process was definitely not smooth for me, but after a lot of googling and multiple tries, I got things to work… at least for a while!
