Installation

machinable is available on PyPI:

bash

$ pip install machinable

Python version

machinable targets modern Python (3.11+)

Optional extras

Extra	Install	Adds
`all`	`pip install machinable[all]`	`numpy` + `pandas`, needed for `Collection.as_dataframe()` and array analysis
`mcp`	`pip install machinable[mcp]`	`fastmcp` + `scipy` + `pandas` for the Agents & MCP server and reference inferences

machinable's index uses the SQLite json1 extension. If your Python's bundled SQLite lacks it you will see:

sqlite3.OperationalError: no such function: json_extract

The simplest fix is to install sqlean.py, which machinable detects and uses automatically:

bash

$ pip install sqlean.py

bash

$ machinable version

Then continue with the Quickstart.
