cogment 2.2.0

Cogment python SDK

cogment-py-sdk

Cogment is an innovative open source AI platform designed to leverage the advent of AI to benefit humankind through human-AI collaboration developed by AI Redefined. Cogment enables AI researchers and engineers to build, train and operate AI agents in simulated or real environments shared with humans. For the full user documentation visit https://docs.cogment.ai

This module, cogment-py-sdk, is the Python SDK for making use of Cogment when working with Python. It's full documentation can be consulted at https://docs.cogment.ai/cogment/cogment-api-reference/python/.

Developers

Local setup

Make sure you have the following installed:

• Python (any version >=3.7 should work),
• Poetry.

Install the dependencies, including downloading and building the cogment protobuf API, by navigating to the python SDK directory and run the following

poetry install

Define used Cogment protobuf API

The version of the used cogment protobuf API is defined in the .cogment-api.yaml file at the root of the repository. The following can be defined:

• cogment_version: "latest", is the default, it retrieves the api from the latest Cogment release (excluding pre-releases),
• cogment_version: "vMAJOR.MINOR.PATCH[-PRERELEASE]", retrieves the api from any Cogment release.
• cogment_api_path: "../RELATIVE/PATH/TO/LOCAL/COGMENT/INSTALL/include/cogment/api", retrieves a local version of the api found at the given path (e.g. common.proto should be at ${cogment_api_path}/common.proto); if set, this overrides cogment_version.

Tests

Integration tests

These tests launch and use Cogment, by default they'll use they'll download and use the latest released version of Cogment.

poetry run task test --launch-orchestrator

The following environment can be defined to change this behavior, either directly in the terminal or in a .env file located at the root of the repository:

COGMENT_PATH="/path/to/cogment" # local path to cogment binary
COGMENT_VERSION="v2.2.0" # cogment version to download

Lint

Run the linter using

poetry run task lint

Check conflicting dependencies with "popular" Python packages

./scripts/check_dependencies_conflicts.sh

This script will check for conflicts required by the cogment-py-sdk and the popular Python packages in the AI/ML/Data ecosystem.

Build the source package

Build the source package (this step will only be succesfull if poetry install succeeded)

poetry build -f sdist

Release process

People having mainteners rights of the repository can follow these steps to release a version MAJOR.MINOR.PATCH. The versioning scheme follows Semantic Versioning.

1. Run ./scripts/create_release_branch.sh MAJOR.MINOR.PATCH to create the release branch and update the version of the package,
2. On the release branch, check and update the changelog if needed,
3. Make sure ./.cogment-api.yaml specifies fixed version to ensure rebuildability,
4. Make sure everything's fine on CI,
5. Run ./scripts/tag_release.sh MAJOR.MINOR.PATCH to create the specific version section in the changelog, merge the release branch in main, create the release tag and update the develop branch with those.

The rest, publishing the package to PyPI and updating the mirror repositories, is handled directly by the CI.
