Installation

Basics

To install LineaPy, run:

pip install lineapy

Or, if you want the latest version of LineaPy directly from the source, run:

pip install git+https://github.com/LineaLabs/lineapy.git --upgrade

Note

By default, LineaPy uses SQLite for artifact store, which keeps the package light and simple. However, SQLite has several limitations, one of which is that it does not support multiple concurrent writes to a database (it will result in a database lock). If you want to use a more robust database, please follow instructions for using PostgreSQL.

Extras

LineaPy offers several extras to extend its core capabilities:

Version	Installation Command	Enables
minimal	pip install lineapy[minimal]	Minimal dependencies for LineaPy
dev	pip install lineapy[dev]	All LineaPy dependencies for testing and development
graph	pip install lineapy[graph]	Dependencies to visualize LineaPy node graph
postgres	pip install lineapy[postgres]	Dependencies to use PostgreSQL backend

Note

The minimal version of LineaPy does not include black or isort, which may result in less organized output code and scripts.

JupyterHub

LineaPy works with JupyterHub!

If LineaPy is installed by an admin, it will be accessible to every user. The admin can set the LineaPy extension to be automatically loaded by adding c.InteractiveShellApp.extensions = ["lineapy"] in ipython_config.py.

If LineaPy is installed by an individual user, it will be accessible to that particular user only as long as they do not have a write permission on the shared environment. In this case, the user will need to run %load_ext lineapy at the top of their session as explained here.
