Environment

zenml.environment

Environment implementation.

Classes

Environment()

Provides environment information.

Individual environment components can be registered separately to extend the global Environment object with additional information (see BaseEnvironmentComponent).

Initializes an Environment instance.

Note: Environment is a singleton class, which means this method will only get called once. All following Environment() calls will return the previously initialized instance.
