Release Notes

[1.1] - 2022-09-06

Release of pyTigerGraph version 1.1.

Added:

  • TensorFlow support for homogeneous GNNs via the Spektral library.

  • Heterogeneous Graph Dataloading support for DGL.

  • Support of lists of strings in dataloaders.

Changed:

  • Fixed KeyError when creating a data loader on a graph where PrimaryIdAsAttribute is False.

  • Error catch if Kafka dataloader doesn’t run in async mode.

  • Refresh schema during dataloader instantiation and featurizer attribute addition.

  • Reduce connection instantiation time.

  • Reinstall query if it is disabled.

  • Confirm Kafka topic is created before subscription.

  • More efficient use of Kafka resources.

  • Allow multiple consumers on the same data.

  • Improved deprecation warnings.

[1.0] - 2022-07-11

Release of pyTigerGraph version 1.0, in conjunction with version 1.0 of the TigerGraph Machine Learning Workbench.

Added:

  • Kafka authentication support for ML Workbench enterprise users.

  • Custom query support for Featurizer, allowing developers to generate their own graph-based features as well as use our built-in Graph Data Science algorithms.

Changed:

  • Additional testing of GDS functionality

  • More demos and tutorials for TigerGraph ML Workbench, found here.

  • Various bug fixes.

[0.9.1] - 2022-06-21

Added new parameter, tgCloud for when connecting to a TigerGraph Cloud instance. Set to True if using a new TigerGraph Cloud

Changed

  • Deprecated gcp parameter, as tgCloud supercedes this. Existing code will be compatible.

[0.9] - 2022-05-16

We are excited to announce the pyTigerGraph v0.9 release! This release adds many new features for graph machine learning and graph data science, a refactoring of core code, and more robust testing. Additionally, we have officially “graduated” it to an official TigerGraph product. This means brand-new documentation, a new GitHub repository, and future feature enhancements.

We are committed to keeping pyTigerGraph true to its roots as an open-source project. Check out the Contributing page and our GitHub Issues page if you want to help with pyTigerGraph’s development.

pyTigerGraph 0.9 was released on May 16th, 2022.

New Features

Graph Data Science Capability

Many new capabilities added for graph data science and graph machine learning.

  • Data loaders for training Graph Neural Networks in DGL and PyTorch Geometric

  • A "featurizer" to generate graph-based features

  • Metric trackers for precision, recall, and accuracy

  • Vertex and edge splitters for generation of train/validation/testing splits.

Other Changes

Documentation

We have moved the documentation to the official TigerGraph Documentation site and updated many of the contents with type hints and more descriptive parameter explanations.

Testing

There is now well-defined testing for every function in the package. A more defined testing framework is coming soon.

Code Structure

A major refactor of the codebase was performed. No breaking changes were made to accomplish this.
