                                                Documentation

                                              See the W&B Developer Guide and API Reference Guide for a full technical description of the W&B platform.

                                                Quickstart

                                              Install W&B to track, visualize, and manage machine learning experiments of any size.

                                                Install the wandb library

                                                pip install wandb

                                                Sign up and create an API key

                                              Sign up for a W&B account. Create a new API key at wandb.ai/settings and store it securely. Optionally, use the wandb login CLI to configure your API key on your machine. You can skip this step -- W&B will prompt you to create an API key the first time you use it.

                                              Note: API keys can only be viewed once when created. Store your API key in a secure location like a password manager or environment variable.

                                                Create a machine learning training experiment

                                              In your Python script or notebook, initialize a W&B run with wandb.init(). Specify hyperparameters and log metrics and other information to W&B.

                                                import wandb
                                                
                                                # Project that the run is recorded to
                                                project = "my-awesome-project"
                                                
                                                # Dictionary with hyperparameters
                                                config = {"epochs": 1337, "lr": 3e-4}
                                                
                                                # The `with` syntax marks the run as finished upon exiting the `with` block,
                                                # and it marks the run "failed" if there's an exception.
                                                #
                                                # In a notebook, it may be more convenient to write `run = wandb.init()`
                                                # and manually call `run.finish()` instead of using a `with` block.
                                                with wandb.init(project=project, config=config) as run:
                                                    # Training code here
                                                
                                                    # Log values to W&B with run.log()
                                                    run.log({"accuracy": 0.9, "loss": 0.1})

                                              Visit wandb.ai/home to view recorded metrics such as accuracy and loss and how they changed during each training step. Each run object appears in the Runs column with generated names.

                                                Integrations

                                              W&B integrates with popular ML frameworks and libraries making it fast and easy to set up experiment tracking and data versioning inside existing projects.

                                              For developers adding W&B to a new framework, follow the W&B Developer Guide.

                                                W&B Hosting Options

                                              Weights & Biases is available in the cloud or installed on your private infrastructure. Set up a W&B Server in a production environment in one of three ways:

                                               1. Multi-tenant Cloud: Fully managed platform deployed in W&B’s Google Cloud Platform (GCP) account in GCP’s North America regions.
                                               2. Dedicated Cloud: Single-tenant, fully managed platform deployed in W&B’s AWS, GCP, or Azure cloud accounts. Each Dedicated Cloud instance has its own isolated network, compute and storage from other W&B Dedicated Cloud instances.
                                               3. Self-Managed: Deploy W&B Server on your AWS, GCP, or Azure cloud account or within your on-premises infrastructure.

                                              See the Hosting documentation in the W&B Developer Guide for more information.

                                                Python Version Support

                                              We are committed to supporting our minimum required Python version for at least six months after its official end-of-life (EOL) date, as defined by the Python Software Foundation. You can find a list of Python EOL dates here.

                                              When we discontinue support for a Python version, we will increment the library’s minor version number to reflect this change.
