What is Launch?โ€‹

W&B Launch is a toolkit for building collaborative, portable, and reproducible machine learning workflows.

Launch workflows can be managed from the W&B CLI, UI, or SDK.

How it worksโ€‹

Launch workflows are powered by three fundamental compoenents: jobs, queues, and agents.

  • Jobs are blueprints for configuring and running the tasks in your ML workflow. A job is actually an Artifact that is created automatically when you track a run with W&B. Each job contains contextual information about the run it is being created from, including the source code, entrypoint, software dependencies, hyperparameters, dataset version, etc.

  • Launch queues are first-in, first-out (FIFO) queues where users can configure and submit their jobs to a particular compute resource. Each item in a launch queue consists of a job and settings for the parameters of that job.

  • Launch agents are long-running processes that poll on one or more launch queues for jobs to run. The agent is capable of building container images to replicate the original environment of the job. The agent can then take the image it has built (or a pre-made image) and execute it on the system targeted by the queue this job was taken from.
