    job: Optional[str] = None,
    config: Optional[Dict[str, Any]] = None,
    template_variables: Optional[Dict[str, Union[float, int, str]]] = None,
    project: Optional[str] = None,
    entity: Optional[str] = None,
    queue_name: Optional[str] = None,
    resource: Optional[str] = None,
    entry_point: Optional[List[str]] = None,
    name: Optional[str] = None,
    version: Optional[str] = None,
    docker_image: Optional[str] = None,
    project_queue: Optional[str] = None,
    resource_args: Optional[Dict[str, Any]] = None,
    run_id: Optional[str] = None,
    build: Optional[bool] = (False),
    repository: Optional[str] = None,
    sweep_id: Optional[str] = None,
    author: Optional[str] = None,
    priority: Optional[int] = None
) -> "public.QueuedRun"
Arguments
uri URI of experiment to run. A wandb run uri or a Git repository URI.
job string reference to a wandb.Job eg: wandb/test/my-job:latest
config A dictionary containing the configuration for the run. May also contain resource specific arguments under the key “resource_args”
template_variables A dictionary containing values of template variables for a run queue. Expected format of {"VAR_NAME": VAR_VALUE}
project Target project to send launched run to
entity Target entity to send launched run to
queue the name of the queue to enqueue the run to
priority the priority level of the job, where 1 is the highest priority
resource Execution backend for the run: W&B provides built-in support for “local-container” backend
entry_point Entry point to run within the project. Defaults to using the entry point used in the original run for wandb URIs, or main.py for git repository URIs.
name Name run under which to launch the run.
version For Git-based projects, either a commit hash or a branch name.
docker_image The name of the docker image to use for the run.
resource_args Resource related arguments for launching runs onto a remote backend. Will be stored on the constructed launch config under resource_args.
run_id optional string indicating the id of the launched run
build optional flag defaulting to false, requires queue to be set if build, an image is created, creates a job artifact, pushes a reference to that job artifact to queue
repository optional string to control the name of the remote repository, used when pushing images to a registry
project_queue optional string to control the name of the project for the queue. Primarily used for back compatibility with project scoped queues

Example:

from wandb.sdk.launch import launch_add

project_uri = "https://github.com/wandb/examples"
params = {"alpha": 0.5, "l1_ratio": 0.01}
# Run W&B project and create a reproducible docker environment
# on a local host
api = wandb.apis.internal.Api()
launch_add(uri=project_uri, parameters=params)
Returns
an instance ofwandb.api.public.QueuedRun which gives information about the queued run, or if wait_until_started or wait_until_finished are called, gives access to the underlying Run information.
Raises
wandb.exceptions.LaunchError if unsuccessful
