Track machine learning experiments with a few lines of code. You can then review the results in an interactive dashboard or export your data to Python for programmatic access using our Public API. Utilize W&B Integrations if you use popular frameworks such as Keras. See W&B Integrations for a full list of integrations and information on how to add W&B to your code.
Experiments dashboard
The image above shows an example dashboard where you can view and compare metrics across multiple runs.

How it works

Track a machine learning experiment with a few lines of code:
  1. Create a W&B Run.
  2. Store a dictionary of hyperparameters, such as learning rate or model type, into your configuration (wandb.Run.config).
  3. Log metrics (wandb.Run.log()) over time in a training loop, such as accuracy and loss.
  4. Save outputs of a run, like the model weights or a table of predictions.
The following code demonstrates a common W&B experiment tracking workflow. Replace my-team with your W&B team entity and my-project-name with your project name.
