Azure Machine Learning SDK v2 for Python. Use for ML workspaces, jobs, models, datasets, compute, and pipelines. Triggers: "azure-ai-ml", "MLClient", "workspace", "model registry", "training jobs", "datasets".
The same skill content is published under more than one repo. The install counts are split across them; any of these commands works.
Client library for managing Azure ML resources: workspaces, jobs, models, data, and compute.
🔑 Two rules apply to every code sample below:
- Prefer
DefaultAzureCredential. It works locally (Azure CLI / VS Code / Developer CLI) and in Azure (managed identity, workload identity) with no code change. Avoid connection strings, account/API keys — they bypass Entra audit and rotation.
- Local dev:
DefaultAzureCredentialworks as-is.- Production: set
AZURE_TOKEN_CREDENTIALS=prod(orAZURE_TOKEN_CREDENTIALS=<specific_credential>) to constrain the credential chain to production-safe credentials.- Wrap every client in a context manager so HTTP transports, sockets, and token caches are released deterministically:
- Sync:
with <Client>(...) as client:- Async:
async with <Client>(...) as client:andasync with DefaultAzureCredential() as credential:(fromazure.identity.aio)Snippets may abbreviate this setup, but production code should always follow both rules.
Long-lived
ml_client: Subsequent examples in this skill assumeml_clientwas created via the pattern above and is alive for the lifetime of your script. In production, wrap your top-level workflow in a singlewith MLClient(...) as ml_client:block so the underlying HTTP transport closes cleanly on exit.
| Property | Operations |
|---|---|
workspaces | create, get, list, delete |
jobs | create_or_update, get, list, stream, cancel |
models | create_or_update, get, list, archive |
data | create_or_update, get, list |
compute | begin_create_or_update, get, list, delete |
environments | create_or_update, get, list |
datastores | create_or_update, get, list, get_default |
components | create_or_update, get, list |
azure.ai.ml sync clients with azure.ai.ml async clients in the same call path. Choose one mode per module.with MLClient(...) as client: (sync) or async with MLClient(...) as client: (async). For async DefaultAzureCredential from azure.identity.aio, also use async with credential: so tokens and transports are cleaned up.| File | Contents |
