Python SDK and CLI for the Renku platform.

Project description

A Python library for the Renku collaborative data science platform. It allows the user to create projects, manage datasets, and capture data provenance while performing analysis tasks.

NOTE:
renku-python is the python library for Renku that provides an SDK and a command-line interface (CLI). It does not start the Renku platform itself - for that, refer to the Renku docs on running the platform.

Installation

Renku releases and development versions are available from PyPI. You can install it using any tool that knows how to handle PyPI packages. Our recommendation is to use :code:pipx.

pipx

First, install pipx and make sure that the $PATH is correctly configured.

$ python3 -m pip install --user pipx
$ pipx ensurepath

Once pipx is installed use following command to install renku.

$ pipx install renku
$ which renku
~/.local/bin/renku

pipx installs renku into its own virtual environment, making sure that it does not pollute any other packages or versions that you may have already installed.

Note

If you install renku as a dependency in a virtual environment and the environment is active, your shell will default to the version installed in the virtual environment, not the version installed by pipx.

To install a development release:

$ pipx install --pip-args pre renku

pip

$ pip install renku

The latest development versions are available on PyPI or from the Git repository:

$ pip install --pre renku
# - OR -
$ pip install -e git+https://github.com/SwissDataScienceCenter/renku-python.git#egg=renku

Use following installation steps based on your operating system and preferences if you would like to work with the command line interface and you do not need the Python library to be importable.

Docker

The containerized version of the CLI can be launched using Docker command.

$ docker run -it -v "$PWD":"$PWD" -w="$PWD" renku/renku-python renku

It makes sure your current directory is mounted to the same place in the container.

Usage

Initialize a renku project:

$ mkdir -p ~/temp/my-renku-project
$ cd ~/temp/my-renku-project
$ renku init

Create a dataset and add data to it:

$ renku dataset create my-dataset
$ renku dataset add my-dataset https://raw.githubusercontent.com/SwissDataScienceCenter/renku-python/master/README.rst

Run an analysis:

$ renku run wc < data/my-dataset/README.rst > wc_readme

Trace the data provenance:

$ renku log wc_readme

These are the basics, but there is much more that Renku allows you to do with your data analysis workflows. The full documentation will soon be available at: https://renku-python.readthedocs.io/

Developing Renku

For development it’s convenient to install renku in editable mode. This is still possible with pipx. First clone the repository and then do:

$ pipx install \
    --editable \
    <path-to-renku-python>[all] \
    renku

This will install all the extras for testing and debugging.

Run tests

To run tests locally with specific version of Python:

$ pyenv install 3.7.5rc1
$ pipenv --python ~/.pyenv/versions/3.7.5rc1/bin/python install
$ pipenv run tests

To recreate environment with different version of Python, it’s easy to do so with the following commands:

$ pipenv --rm
$ pyenv install 3.6.9
$ pipenv --python ~/.pyenv/versions/3.6.9/bin/python install
$ pipenv run tests

Using External Debuggers

To run renku via e.g. the Visual Studio Code debugger you need run it via the python executable in whatever virtual environment was used to install renku. If there is a package needed for the debugger, you need to inject it into the virtual environment first, e.g.:

$ pipx inject renku ptvsd

Finally, run renku via the debugger:

$ ~/.local/pipx/venvs/renku/bin/python -m ptvsd --host localhost --wait -m renku.cli <command>

If using Visual Studio Code, you may also want to set the Remote Attach configuration PathMappings so that it will find your source code, e.g.

{
        "name": "Python: Remote Attach",
        "type": "python",
        "request": "attach",
        "port": 5678,
        "host": "localhost",
        "pathMappings": [
            {
                "localRoot": "<path-to-renku-python-source-code>",
                "remoteRoot": "<path-to-renku-python-source-code>"
            }
        ]
    },

Changes

0.10.0 (2020-03-25)

This release brings about several important Dataset features:

  • importing renku datasets (#838)
  • working with data external to the repository (#974)
  • editing dataset metadata (#1111)

Please see the Dataset documentation for details.

Additional features were implemented for the backend service to facilitate a smoother user experience for dataset file manipulation.

IMPORTANT: starting with this version, a new metadata migration mechanism is in place (#1003). Renku commands will insist on migrating a project immediately if the metadata is found to be outdated.
