The starter app is deployed at https://fastai-v3.onrender.com.
Fork the starter app on GitHub.
Fork https://github.com/render-examples/fastai-v3 into your GitHub account.
Create a Render account
Sign up for a Render account. You don’t need a credit card to get started.
If you just want to test initial deployment on Render, the starter repo is set up to use Jeremy’s bear classification model from Lesson 2 by default. If you want to use your own model, keep reading.
Upload your trained model file
Upload the trained model file created with
learner.export (for example
export.pkl) to a cloud service like Google Drive or Dropbox. Copy the download link for the file.
Note the download link should start the file download directly—and is typically different from the share link (which presents you with a view to download the file).
Customize the app for your model
- Edit the file
appdirectory and update the
model_file_urlvariable with the URL copied above.
- In the same file, update the line
classes = ['black', 'grizzly', 'teddys']with the classes you expect from your model.
Commit and push your changes to GitHub.
Make sure to keep the GitHub repo you created above current. Render integrates with your GitHub repo and automatically builds and deploys changes every time you push a change.
Create a new Web Service on Render and use the repo you created above. You will need to grant Render permission to access your repo in this step.
On the deployment screen, pick a name for your service and use
Dockerfor the Environment. The URL will be created using this service name. The service name can be changed if necessary, but the URL initially created can’t be edited.
Click Save Web Service. That’s it! Your service will begin building and should be live in a few minutes at the URL displayed in your Render dashboard. You can follow its progress in the deploy logs.
Your app’s URL will look like
https://service-name.onrender.com. You can also monitor the service logs as you test your app.
To run the app server locally, run this command in your terminal:
python app/server.py serve
If you have Docker installed, you can test your app in the same environment as Render’s by running the following command at the root of your repo:
docker build -t fastai-v3 . && docker run --rm -it -p 5000:5000 fastai-v3
Go to http://localhost:5000/ to test your app.
