End-to-end tutorial
Model deployment works in three stages:
- 1.Package your model into a Truss
- 2.Configure the Truss to serve your model
- 3.Deploy the Truss, containing your packaged model, on the platform of your choice
Truss is a seamless bridge between model development and model deployment
Truss is useful after you have a trained machine learning model that you are happy with and want to deploy. You can build a Truss from a pickled or otherwise saved model, or from an in-memory model. So to follow this guide, you will need one of the following:
- An in-memory machine learning model (most useful for supported frameworks listed below), or
- A serialized model, or
- A script to download, create, or otherwise generate one of the previous options
If you want to follow this tutorial for a particular framework and don't have a model, no worries! Each of the Truss creation tutorials linked in step 1 features sample code for a ML model in the appropriate framework.
Truss works across model frameworks, and the most common model frameworks are supported with the one-line
create command. Click the framework you built your model in to see specific packaging instructions for that format.For the following formats, if you have an in-memory trained model object
model, just call the following:from truss import create
create(model, target_directory="my_truss")
Supported frameworks:
A model built in framework not listed, or built without a framework, can still be packaged and used as a Truss. You'll just need to build the Truss manually.
In the most straightforward cases, you can skip this step entirely. For example, the Truss created from the scikit-learn tutorial model, a simple random forest classifier on the Iris data set, is ready to deploy as-is. For more complex use cases, some configuration is required, but don't worry, we're not dropping you off the deep end to do your own MLOps. Truss configuration should take little time and use familiar tools.
Before deploying your model in its Truss, try serving it locally to make sure everything is working as expected. If not, work through the following brief configuration guides as needed:
You can deploy a Truss anywhere that can run a Docker image, as well as purpose-built platforms like Baseten.
Once your Truss is configured, it doesn't matter what framework your model was written in, only that you are deploying to a platform that can provision the resources your model needs. We have step-by-step deployment guides for the following platforms:
