The following shows the process of uploading, deploying, publishing, and edge deploying a model with Wallaroo for ARM deployment with Nvidia Jetson acceleration . The example uses a Computer Vision Resnet50 model in the ONNX framework.

The first step is to upload the model, setting the architecture and AI accelerator.

model = wl.upload_model(
                        name="computer-vision-resnet50-arm",
                        path= './models/frcnn-resnet.pt.onnx', 
                        framework=Framework.ONNX,
                        arch=wallaroo.engine_config.Architecture.ARM,
                        accel=wallaroo.engine_config.Acceleration.Jetson)

display(model)

With the model uploaded, we deploy it by:

• Adding the model to a pipeline as a pipeline step.
• Setting the deployment configuration - the resources allocated to the model from the cluster. For this example, we allocate 1 CPU and 2 Gi RAM. Note that we do not specify what type of accelerator or processor architecture is used - this is set at the model level.
• Deploying the model. At this point, the model is ready to accept inference requests until it is undeployed.

pipeline_arm = wl.build_pipeline('acceleration-demonstration-arm')
pipeline_arm.clear()
pipeline_arm.add_model_step(arm_model)

deployment_config = wallaroo.DeploymentConfigBuilder() \
    .replica_count(1) \
    .cpus(1) \
    .memory("2Gi") \
    .build()

pipeline_arm.deploy(deployment_config = deployment_config)
display(pipeline_arm)

Publishing the model stores a copy of the model and the inference engine in an OCI (Open Container Initiative) Registry that is set by the Wallaroo platform operations administrator. Once published, it is ready for deployment in any edge or multi-cloud environment with the same AI Accelerator and Architecture settings.

A template of the docker run command is included with the publish return.

We now publish the pipeline. Note that the Engine Config inherited the acceleration from the model.

# default deployment configuration
pub_arm = pipeline_arm.publish(deployment_config=deployment_config)
display(pub_arm)

Waiting for pipeline publish... It may take up to 600 sec.
Pipeline is publishing....... Published.

docker run \
    -p $EDGE_PORT:8080 \
    -e OCI_USERNAME=$OCI_USERNAME \
    -e OCI_PASSWORD=$OCI_PASSWORD \
    -e PIPELINE_URL=registry.example.com/uat/pipelines/acceleration-demonstration-arm:890b56ee-2a0e-4ed1-ae96-c021ca801a7e \
    -e CONFIG_CPUS=1 registry.example.com/uat/engines/proxy/wallaroo/ghcr.io/wallaroolabs/fitzroy-mini-aarch64:v2024.2.0-main-4870

helm install --atomic $HELM_INSTALL_NAME \
    oci://registry.example.com/uat/charts/acceleration-demonstration-arm \
    --namespace $HELM_INSTALL_NAMESPACE \
    --version 0.0.1-890b56ee-2a0e-4ed1-ae96-c021ca801a7e \
    --set ociRegistry.username=$OCI_USERNAME \
    --set ociRegistry.password=$OCI_PASSWORD

Once published, the model is deployed on edge or multi-cloud environments through the docker run template. Before deploying, the following environmental variables are set:

• $EDGE_PORT: The network port used to submit inference requests to the deployed model.
• $OCI_USERNAME: The user name or identifier to authenticate to the OCI (Open Container Initiative) Registry where the model was published.
• $OCI_PASSWORD: The password or token to authenticate to the OCI (Open Container Initiative) Registry where the model was published.

For ML models deployed on Jetson accelerated hardware via Docker, the application docker is replace by the nvidia-docker application. For details on installing nvidia-docker, see Installing the NVIDIA Container Toolkit. For example:

nvidia-docker run \
    -p $EDGE_PORT:8080 \
    -e OCI_USERNAME=$OCI_USERNAME \
    -e OCI_PASSWORD=$OCI_PASSWORD \
    -e PIPELINE_URL=registry.example.com/uat/pipelines/acceleration-demonstration-arm:890b56ee-2a0e-4ed1-ae96-c021ca801a7e \
    registry.example.com/uat/engines/proxy/wallaroo/ghcr.io/wallaroolabs/fitzroy-mini-aarch64:v2024.2.0-main-4870

Once deployed, the model is ready to accept inference requests through the specified $EDGE_PORT.
