There’s a TensorFlow talk on YouTube about GNNs by Petar Veličković (DeepMind) with a demo that uses Spektral:

Note that since the library has changed since the video was created, there’re some code changes too (check the comments under the YouTube video). For example, in the beginning this could work in v1.0.x:

"The focus of the graph package presented here is on a neat integration of graphs into the TensorFlow-Keras framework in the most straightforward way. Thereby, we hope to provide Keras graph layers which can be quickly rearranged, changed and extended to build custom graph models with little effort. This implementation is focused on the new TensorFlow’s RaggedTensor class which is most suited for flexible data structures such as graphs and natural language.”

Last year, there was a Google Graph Mining and Learning workshop at NeurIPS 2020: https://gm-neurips-2020.github.io/ - there were some insightful talks, check out the link.

We really appreciate the community contributions in GNNs listed above, thanks! Today we released a TF GNN library which is available on the TensorFlow GItHub repo here, and explained the background of this library in a blog post.
