Development

Prerequisites

• Python 3.10+

Setup

All commands below should be run from the python/ directory:

cd python

Install local (editable) + run

python3 -m venv .venv
source .venv/bin/activate
python -m pip install -U pip

# Install in editable mode
pip install -e .

# Run
mem0 --help
mem0 version

After moving to the new directory structure: If you previously had the CLI installed from the old repo root, you need to re-run pip install -e . from inside the python/ directory to pick up the new location.

Run without installing globally

This still installs the package into your active virtualenv (editable), but you can invoke it via module execution:

source .venv/bin/activate
pip install -e .
python -m mem0_cli --help

Optional extras

OSS integration extras

pip install -e ".[oss]"

Dev tools (tests/lint)

pip install -e ".[dev]"

Run tests

pip install -e ".[dev]"
