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.

Convert an Exception to a HTTP error response.

Uses the REST_API_EXCEPTIONS list to determine the appropriate status code associated with the exception type. The exception class name and arguments are embedded in the HTTP error response body.

The lookup uses the first occurrence of the exception type in the list. If the exception type is not found in the list, the lookup uses isinstance to determine the most specific exception type corresponding to the supplied exception. This allows users to call this method with exception types that are not directly listed in the REST_API_EXCEPTIONS list.

Parameters:
