PyTorch Geometric provides graph neural network tools and libraries for PyTorch projects.
VectorFlow
Minimalist neural network library optimized for sparse data and single machine environments.

About VectorFlow
VectorFlow is an open-source neural network library distributed as a D dub package on GitHub. It is optimized for sparse data and single-machine environments, has no library dependencies beyond a recent D compiler, and is tested on Linux and macOS. The repository includes an RCV1 sparse logistic regression example, runs tests with dub test, and provides documentation through ddoc and the repository wiki; LDC is recommended for the fastest runtime speed.
