Database

PostgreSQL database adapter for the Python programming language

psycopg2 Psycopg is the most popular PostgreSQL database adapter for the Python programming language. Its main features are the complete implementation of the Python DB API 2.0 specification and the thread safety (several threads can share the same connection). It was designed for heavily multi-threaded applications that create and destroy lots of cursors and make a large number of concurrent “INSERT”s or “UPDATE”s. Psycopg 2 is mostly implemented in C as a libpq wrapper, resulting in being both efficient and […]

PyTorch library for training Submanifold Sparse Convolutional Networks

SparseConvNet Submanifold Sparse Convolutional NetworksThis is the PyTorch library for training Submanifold Sparse Convolutional Networks. Spatial sparsity This library brings Spatially-sparse convolutional networks to PyTorch. Moreover, it introduces Submanifold Sparse Convolutions, that can be used to build computationally efficient sparse VGG/ResNet/DenseNet-style networks. With regular 3×3 convolutions, the set of active (non-zero) sites grows rapidly: With Submanifold Sparse Convolutions, the set of active sites is unchanged. Active sites look at their active neighbors (green); non-active sites (red) have no computational overhead: […]
