Overview

Install

note

This step is only required if you're running fused on your end (locally or in a development environment). If you're working in Workbench UDF Builder or App Builder fused is already installed for you.

1. Set up a Python environment:

We're using venv but you could use conda or any other environment manager in Python.

python3 -m venv .venv
source .venv/bin/activate

2. Install the fused package:

pip install fused

3. Authenticate:

In a notebook

from fused.api import NotebookCredentials
credentials = NotebookCredentials()

Run this snippet from a Notebook Cell and follow the authentication flow, which will store a credentials file in ~/.fused/credentials.
