Build ML Model Containers. Automatically.

Turn your machine learning models into portable container images that can run just about anywhere using Chassis. For a deeper dive and better understanding of what Chassis is, learn more here.


Easy to Connect Requires Installation
Quickest and easiest way to start using Chassis.
No DevOps experience required.

Preferred

Connect to Chassis Service

More involved installation.
Requires a moderate understanding of
Kubernetes, Helm, and Docker.


Install Chassis on Your Machine

How it Works

After connecting to the Chassis service, your workflow will involve a few simple steps:

Set Up Environment

Create your workspace environment, open a Jupyter Notebook or other Python editor, and install the Chassisml SDK.

pip install chassisml

Load Your Model

Train your model or load your pre-trained model into memory (.pth, .pkl, .h5, .joblib, or other file format - all model types and formats are supported!).

model = framework.load("path/to/model.file")

Write Process Function

The process function will use your model to perform any required preprocessing and inference execution on the incoming input_bytes data. 

def process(input_bytes):
  # preprocess
  data = preprocess(input_bytes)

  # run inference
  predictions = model.predict(data)

  # post process predictions
  formatted_results = postprocess(predictions)

  return formatted_results

Initialize Client and Create Chassis Model

NOTE: Depending on how you connect to the service, you will need to identify the URL on which the service is running and can be accessed. If you are connecting to the publicly-hosted version, make sure to sign up to access this URL. Otherwise if you are deploying manually and connecting to a locally running instance, your URL will look something like http://localhost:5000.

Once you have this URL, replace <chassis-instance-url> in the below line with your URL.

chassis_client = chassisml.ChassisClient("<chassis-instance-url>")
chassis_model = chassis_client.create_model(process_fn=process)

Publish Chassis Model

response = chassis_model.publish(
    model_name="Sample ML Model",
    model_version="0.0.1",
    registry_user=dockerhub_user,
    registry_pass=dockerhub_pass,
)

Run and Query Model

Run your model locally or on your preferred serving platform and begin making inference calls right away.
