After creating the Azure resource, use the W&B Python SDK for experiment tracking:
# Install: pip install wandb
import wandb
# Login with your W&B API key from the Azure-deployed instance
wandb.login(host="https://my-company-wandb.wandb.ai")
# Initialize a run
run = wandb.init(project="my-ml-project")
# Log metrics
wandb.log({"accuracy": 0.95, "loss": 0.05})
# Finish run
run.finish()
