# Step #3: Set up Weights and Biases

Weights and Biases is an MLOps platform that allows you to visualize and optimize your ML models with better experiment tracking, dataset versioning and model management. This step is optional but recommended since we will be using Weights and Biases to visualize the model accuracy and training speed throughout the lab.
