Examples

Usage

Prerequisites

Setup a Python virtual environment:

virtualenv -p python3 venv/
# Alternative: python3 -m venv venv/

Install packages:

pip install -r requirements.txt

# Optional:
pip install -r requirements_full.txt  # for specific backends
pip install -r requirements_dev.txt  # for linting, testing,...

Demo

Package installation: TODO

Make sure to add the top level directory of this repository to your Python path:

export PYTHONPATH=$(pwd):$PYTHONPATH

Minimal example:

python3 -m isaac_toolkit.session.create --session sess/
python3 -m isaac_toolkit.session.summary --session sess/

See Examples/standalone/coremark/README.md for an end-to-end example.

Development

Style

We use the black formatter to maintain a consistent Python style (See setup.cfg & pyproject.toml)

Pylint config is also available, but not enforced.

Testing

First, make sure that the additional development packages are installed via:

pip install -r requirements_dev.txt

Run Pytest:

python3 -m pytest tests -rs -s

Create Coverage Report:

coverage run --source isaac_toolkit -m pytest tests
coverage report -m
coverage html
