Installation

This installation description is for the general user. If you are using the Belle II software, see below:

  1. Setup your local environment. For example, run:

    source venv/bin/activate

  2. Install b2luigi from pipy into your environment.

    1. If you have a local installation, you can use the normal setup command
    python -m pip install b2luigi
    1. If this fails because you do not have write access to where your virtual environment lives, you can also install b2luigi locally:
    python -m pip install --user b2luigi

    This will automatically also install luigi into your current environment. Please make sure to always setup your environment correctly before using b2luigi.

Now you can go on with the :ref:`quick-start-label`.

b2luigi and Belle II

  1. Setup your local environment. You can use a local environment (installed on your machine) or a release on cvmfs. For example, run:

    source /cvmfs/belle.cern.ch/tools/b2setup prerelease-02-00-00c

    Or you setup your local installation

    cd release-directory
source tools-directory/b2setup

  2. Install b2luigi from pipy into your environment.

    1. If you have a local installation, you can use the normal setup command
    python -m pip install b2luigi --upgrade
    1. If you are using an installation from cvmfs, you need to add the user flag.
    python -m pip install --user b2luigi --upgrade

Attention!

The examples in this documentation are all shown with calling python, assuming this refers to the Python 3 executable of their (virtual) environment. In some systems and e.g. basf2 environments, python refers to Python 2 (not supported by b2luigi). Then, python3 should be used instead.

Please also have a look into the :ref:`basf2-example-label`.
