# install dmlab
sh install-dmlab2d.sh

# build wheel
cd lab2d
bazel build --config=lua5_2 --verbose_failures //dmlab2d:dmlab2d_wheel

# test run
bazel run -c opt --config=lua5_2 --verbose_failures dmlab2d/random_agent -- --level_name=clean_up

# go back to enclosing folder and install meltingpot
cd ..
sh install-meltingpot.sh

# test it
pytest meltingpot

# From the docs:
# NOTE: If you get a ModuleNotFoundError: No module named 'meltingpot.python' error, you can solve it by exporting the meltingpot home directory as PYTHONPATH (e.g. by calling export PYTHONPATH=$(pwd))
