The following steps have to be done for both cases

• Build SystemDS with maven first mvn package -DskipTests, with the working directory being SYSTEMDS_ROOT (Root directory of SystemDS)
• cd to this folder (basically SYSTEMDS_ROOT/src/main/python

If we want to build the package for uploading to the repository via python3 -m twine upload --repository-url [URL] dist/* (will be automated in the future)

• Run create_python_dist.py

python3 create_python_dist.py

• now in the ./dist directory there will exist the source distribution systemds-VERSION.tar.gz and the wheel distribution systemds-VERSION-py3-none-any.whl, with VERSION being the current version number
• Finished. We can now upload it with python3 -m twine upload --repository-url [URL] dist/*

If we want to build the package just locally for development, the following steps will suffice

• Run pre_setup.py (this will copy lib and systemds-VERSION-SNAPSHOT.jar)

python3 create_python_dist.py

• Finished. Test by running a test case of your choice:

python3 tests/test_matrix_binary_op.py
