Environment

`zenml.environment`

Environment implementation.

`BaseEnvironmentComponent`

Base Environment component class.

All Environment components must inherit from this class and provide a unique value for the NAME attribute.

Different code components can independently contribute with information to the global Environment by extending and instantiating this class:

from zenml.environment import BaseEnvironmentComponent

MY_ENV_NAME = "my_env"

class MyEnvironmentComponent(BaseEnvironmentComponent):

    NAME = MY_ENV_NAME

    def __init__(self, my_env_attr: str) -> None:
        super().__init__()
        self._my_env_attr = my_env_attr

    @property
    def my_env_attr(self) -> str:
        return self._my_env_attr

my_env = MyEnvironmentComponent()

There are two ways to register and deregister a BaseEnvironmentComponent instance with the global Environment:

by explicitly calling its activate and deactivate methods:

my_env.activate()

# ... environment component is active
# and registered in the global Environment

my_env.deactivate()

# ... environment component is not active

by using the instance as a context:

with my_env:
    # ... environment component is active
    # and registered in the global Environment

# ... environment component is not active

While active, environment components can be discovered and accessed from the global environment:

from foo.bar.my_env import MY_ENV_NAME
from zenml.environment import Environment

my_env = Environment.get_component(MY_ENV_NAME)

# this works too, but throws an error if the component is not active:

my_env = Environment[MY_ENV_NAME]

Attributes:

Name	Type	Description
`NAME`	`str`	a unique name for this component. This name will be used to register this component in the global Environment and to subsequently retrieve it by calling `Environment().get_component`.
