Controlling model states¶
This library enables you to control models by setting their state. For example, you may want to set a model to have state “production.” You can then query the model store for models by state, and change model states.
The examples below assume you have created a model store instance already:
from modelstore.model_store import ModelStore model_store = ModelStore.from_aws_s3(bucket_name)
Create a state¶
Before doing anything with a model state, you need to create it. This is a one-time operation.
production_state = "production" model_store.create_model_state(production_state)
Set and unset a model’s state¶
Once a state has been created, you can add a model to a state. You can add a model to more than one state, and you can add more than one model to a state.
model_domain = "my-domain" model_id = "my-model-id" production_state = "production" model_store.set_model_state(model_domain, model_id, state_name)
To unset a model’s state, you can use:
model_store.remove_model_state(model_domain, model_id, state_name)
Find models by state¶
After setting the state of one or more models, you can find them by adding the state name to the list versions function:
model_ids = modelstore.list_versions( model_domain, state_name=production_state )
