Zen Server

zenml.zen_server special

ZenML Server Implementation.

The ZenML Server is a centralized service meant for use in a collaborative setting in which stacks, stack components, flavors, pipeline and pipeline runs can be shared over the network with other users.

You can use the zenml server up command to spin up ZenML server instances that are either running locally as daemon processes or docker containers, or to deploy a ZenML server remotely on a managed cloud platform. The other CLI commands in the same zenml server group can be used to manage the server instances deployed from your local machine.

To connect the local ZenML client to one of the managed ZenML servers, call zenml server connect with the name of the server you want to connect to.

password Optional[str]

The password.

access_token Optional[str]

The access token.

Convert an Exception to a HTTP error response.

OAuth2 device authorization endpoint.

This endpoint implements the OAuth2 device authorization grant flow as defined in https://tools.ietf.org/html/rfc8628. It is called to initiate the device authorization flow by requesting a device and user code for a given client ID.

For a new client ID, a new OAuth device is created, stored in the DB and returned to the client along with a pair of newly generated device and user codes. If a device for the given client ID already exists, the existing DB entry is reused and new device and user codes are generated.

Parameters:

make_dependable(cls)

This function makes a pydantic model usable for fastapi query parameters.

Additionally, it converts InternalServerErrors that would happen due to pydantic.ValidationError into 422 responses that signal an invalid request.

Check out https://github.com/tiangolo/fastapi/issues/1474 for context.

!!! usage def f(model: Model = Depends(make_dependable(Model))): ...

UPDATE: Function from above mentioned Github issue was extended to support multi-input parameters, e.g. tags: List[str]. It needs a default set to Query(), rather just plain .

Parameters:

Name Type Description Default
cls Type[pydantic.main.BaseModel]

The model class.
