The W&B Python SDK, accessible at wandb, enables you to train and fine-tune models, and manage models from experimentation to production.
After performing your training and fine-tuning operations with this SDK, you can use the Public API to query and analyze the data that was logged, and the Reports and Workspaces API to generate a web-publishable report summarizing your work.
