# Creating the pip package involves the following steps:
# - Define the pip package related files - setup.py (this file) and MANIFEST.in by:
# 1. Make sure all the requirements in install_requires are defined correctly and that their version is the correct one
# 2. Add all the non .py files to the package_data and to the MANIFEST.in file
# 3. Make sure that all the python directories have an __init__.py file

# - Check that everything works fine by:
# 1. Create a new virtual environment using `virtualenv coach_env -p python3`
# 2. Run `pip install -e .`
# 3. Run `coach -p CartPole_DQN` and make sure it works
# 4. Run `dashboard` and make sure it works

# - If everything works fine, build and upload the package to PyPi:
# 1. Update the version of Coach in the call to setup()
# 2. Remove the directories build, dist and rl_coach.egg-info if they exist
# 3. Run `python setup.py sdist`
# 4. Run `twine upload dist/*`
