Contributing to turi-code/how-to

A how-to is a small code snippet (roughly 2-15 lines of actual code) that shows how to accomplish a specific task with GraphLab Create. It may include the use of other Python packages (such as Pandas, matplotlib, etc.) when relevent. The content of a how-to should be an example of something that is not obvious to someone experienced in Python (like getting the length of an object), but not too complex as to warrant a larger piece (blog post, user guide chapter, etc.).

Contributor guidelines


All contents of pull requests must conform to the CC0 1.0 Universal license. Any changes submitted will be licensed under this license.

Content and style guidelines

How-to examples should consist of code and comments in a .py file.

  • The whole .py file should be runnable as a program. The code should not rely on any implicit or global state.

  • When possible, datasets that are used should be accessible via a public (http or S3) URL or synthetically created in the example.

  • When importing graphlab, import graphlab as gl.

  • All required external (non-GraphLab Create and non-builtin) Python packages should have a comment at the top, to direct the user how to install:

    # Requires 'pip install python-dateutil==1.5'
  • Use capital letters at the beginning of each comment. Punctuation at the end is not required.

  • Use a comment to explain the presence of any magic number

New how-tos

We welcome suggestions for new how-to examples for GraphLab Create. Please submit a pull request. The guidelines for writing how-to examples apply. Additionally, please add a link to the readme with a title and a link to your example. If the how-to does not fit into one of the categories already present, then please add a new category.

Changes to existing how-tos

We welcome pull requests for changes to existing how-tos. Such a change should ideally make the example more clear, more correct, and/or simpler.
