Installing Haute¶

Make sure you've set up your environment first (VS Code, Python, uv).

Create a project and install Haute¶

Open the VS Code terminal and run these commands one at a time:

uv init my-pricing-project
cd my-pricing-project
uv add haute
haute init --target databricks

This creates a new project folder with everything Haute needs: a haute.toml configuration file, test quote templates, CI/CD workflow files, and a .env.example credential template.

Set up a virtual environment and run¶

uv venv
.venv\Scripts\activate
uv sync
haute serve

You'll see (.venv) appear in your terminal prompt after the activate step - that means the virtual environment is active. haute serve opens the Haute visual editor in your browser. If you see it, you're all set.

What is a virtual environment?

A virtual environment is a private space for your project's packages. Without one, installing packages would change your whole computer's Python setup. With a virtual environment, each project gets its own isolated set of packages. You activate it each time you open a new terminal.

Installing extras¶

Depending on your deploy target, you may need additional packages:

uv add "haute[databricks]"         # Adds mlflow + databricks-sdk (for Databricks target)

Troubleshooting¶

haute serve doesn't open anything in my browser

Look at the terminal output for a line like Running on http://127.0.0.1:8000. Copy that address and paste it into your browser. If you see an error, make sure your virtual environment is active ((.venv) in your prompt).

(.venv) isn't showing in my terminal prompt

Run .venv\Scripts\activate. You need to do this every time you open a new terminal window.

What's next?¶

You've got Haute running locally. From here:
