[Queja] Error en deploy

Hola quiero hacer el deploy :

import os
deployer=ModelDeployer()
deployer.deploy(
    model_id=model_id,
    display_name="API del modelo de clasificacion de EAC",
    instance_shape="VM.Standard.E4.Flex",
    instance_count=1,
    project_id=os.environ['PROJECT_OCID'],
    compartment_id=os.environ['TENANCY_OCID'])

pero me da error:
