A PostgreSQL or SQLite orm for Python

Prom An opinionated lightweight orm for PostgreSQL or SQLite. Prom has been used in both single threaded and multi-threaded environments, including environments using Greenthreads. 1 Minute Getting Started with SQLite First, install prom: $ pip install prom Set an environment variable: $ export PROM_DSN=sqlite://:memory: Start python: $ python Create a prom Orm: >>> import prom >>> >>> class Foo(prom.Orm): … table_name = “foo_table_name” … bar = prom.Field(int) … >>> Now go wild and create some Foo objects: >>> for x […]

Write Pythonic and Clean Code With namedtuple

Python’s collections module provides a factory function called namedtuple(), which is specially designed to make your code more Pythonic when you’re working with tuples. With namedtuple(), you can create immutable sequence types that allow you to access their values using descriptive field names and the dot notation instead of unclear integer indices. If you have some experience using Python, then you know that writing Pythonic code is a core skill for Python developers. In this tutorial, you’ll level up that […]

A rotation-equivariant GNN for learning from biomolecular structure

Geometric Vector Perceptron Implementation of equivariant GVP-GNNs as described in Learning from Protein Structure with Geometric Vector Perceptrons by B Jing, S Eismann, P Suriana, RJL Townshend, and RO Dror. This repository serves two purposes. If you would like to use the GVP architecture for structural biology tasks, we provide building blocks for models and data pipelines. If you are specifically interested in protein design as described in the paper, we provide scripts for training and testing models. Note: This […]

Deep Face Detection Library in TensorFlow for Python

RetinaFace RetinaFace is the face detection module of insightface project. The original implementation is mainly based on mxnet. Then, its tensorflow based re-implementation is published by Stanislas Bertrand. This repo is heavily inspired from the study of Stanislas Bertrand. Its source code is simplified and it is transformed to pip compatible but the main structure of the reference model and its pre-trained weights are same. Installation The easiest way to install retinaface is to download it from pypi. pip install […]
