You can also use [`tilt`](https://tilt.dev/) along with `pack` and [`paketo`](https://paketo.io/) Buildpacks allowing you make code changes and have them reflected live in your custom inference service. For more details see - [Paketo Python Buildpacks - Enable Process Reloading](https://paketo.io/docs/howto/python/#enable-process-reloading)

This looks cool, you can create the Tiltfile like following for continuous dev development, we might want to add a bit more instruction for how to do this.

load('ext://pack', 'pack')
k8s_kind('InferenceService', api_version='serving.kserve.io/v1beta1', image_json_path='{.spec.predictor.containers[*].image}')

allow_k8s_contexts('docker-desktop')

pack(
  'yuzisun/tilt-demo-2022',
  ignore=[
    'Tiltfile',
    'service.yaml',
    '.*',
  ],
  live_update = [
    sync('.', '/workspace'),
  ],
  deps=["."],
)
k8s_yaml('service.yaml')
k8s_resource('tilt-demo', extra_pod_selectors={'serving.kserve.io/inferenceservice':'tilt-demo'})

The tiltfile I am using looks a bit like -

# -*- mode: Python -*-

version_settings(constraint='>=0.22.1')
load('ext://pack', 'pack')
docker_compose('docker-compose.yml')

pack('myapp',
  builder="paketobuildpacks/builder:full",
  live_update=[
    sync('.', '/workspace'),
  ]
)
