Hub Class

Note

This is an experimental class, and may change at any time. Please see https://aka.ms/azuremlexperimental for more information.

A Hub is a special type of workspace that acts as a parent and resource container for lightweight child workspaces called projects. Resources like the hub's storage account, key vault, and container registry are shared by all child projects.

As a type of workspace, hub management is controlled by an MLClient's workspace operations.

Creating a Hub object.

   from azure.ai.ml.entities import Hub

   ws = Hub(name="sample-ws", location="eastus", description="a sample workspace hub object")

Methods

dump	Dump the workspace spec into a file in yaml format.

dump

Dump the workspace spec into a file in yaml format.

dump(dest: str | PathLike | IO, **kwargs: Any) -> None

Parameters

Name	Description
dest Required	Union[<xref:PathLike>, str, IO[AnyStr]] The destination to receive this workspace's spec. Must be either a path to a local file, or an already-open file stream. If dest is a file path, a new file will be created, and an exception is raised if the file exists. If dest is an open file, the file will be written to directly, and an exception will be raised if the file is not writable.
