PyDAO is very thin object-relational mapper similar to Hibernate (but much simpler). Created to speed-up application development. It's very simple, but powerful, based on POPO (Plain Old Python Objects). Uses DB-API to connect to SQL databases.

PyExPsiN is a Python crossplatform (Linux/Windows) module for made easy writing psychological experiments. Right now includes functions for DMTS (Delayed Matching to Sample), N-Back, Spatial N-Back, "Grammatical", Mixed Dots, Stroop, and more.

This project aims at creating an IDE framework, which allows programmers to manage with keyboard only. This project extends the multi-pane environment concept (as followed by the traditional Unix Emacs and vi editors) to include graphical output.

Pyhew is a web framework written in python aiming to ease the web development with python. Based on frameworks like smarty and php2go. Provides a Templating system, forms (with xml for html and validation), url routing and more.

General and simple IRC bot framework with very flexible bus architecture and plugins support, originally written for use as RPC gateway for remote message sending to multiple IRC channels or users. Now: http://github.com/martinkozak/pyircgate-daemon.

Middleware Oriented Message (Publish and Subscribe) implemented in Python

PyMultimethods is a library that allows multimethods (aka multiple dispatch, generic functions) to be written in the python programming language. Functionality is exposed via function decorator or, optionally, a direct class interface.

Python bindings for OpenCL, the open standard for parallel programming of heterogeneous systems

PyOptFrame-LEGACY is a Python version of OptFrame v2, proposed in 2011, now superseeded in 2021 by v5 on GitHub and PIP. The main objective is to provide the same interface to OptFrame C++ optimization framework, including classic metaheuristics such as genetic algorithms, simulated annealing, variable neighborhood search, first/best/multi-improvement, hill climbing, and multi-objective methods such as nsga-ii. See NEWEST version v5 on GitHub and PIP. Please try Official pyoptframe on https://pypi.org/project/optframe/ for OptFrame v5 (last updated 2022).

PyPLE (pronounced "pipple") is the Python Persistent Logic Engine -- a framework for composing, evaluating, and storing logical expressions.

PyPlayground is an environment for developing algorithms involving movement in a space of up to three dimensions using Python.

The PyQt4D (Python Qt for Designer) is an Open Source Project making Qt Designer full-featured RAD (Rapid Application Development) tool to develop data-aware two- or multi-tier applications using Python language and Qt library.

Python wrapper for Sword library. Helps python users access sword publications (mostly bibles, commentaries, etc). Also will include a supybot biblebot plugin. There is already a swig generated wrapper to pysword and python based bible reader here: http:

PySys is a Python based framework for the organisation and execution of system level automated and manual testcases. PROJECT MOVED: As of April 2019, PySys has moved to GitHub and is no longer maintained on SourceForge, so for the development project go to https://github.com/pysys-test/pysys-test or for end-users of PySys go to https://pypi.org/project/PySys/

This project is an XML oriented Web Framework that relies on python for expansion of XML data into web pages, while keeping code and content sepearted. Coupling this with CSS allows for complete page formatting and styling without touching python code

PyText is a deep-learning based NLP modeling framework built on PyTorch. PyText addresses the often-conflicting requirements of enabling rapid experimentation and of serving models at scale. It achieves this by providing simple and extensible interfaces and abstractions for model components, and by using PyTorch’s capabilities of exporting models for inference via the optimized Caffe2 execution engine. We use PyText at Facebook to iterate quickly on new modeling ideas and then seamlessly ship them at scale. Distributed-training support built on the new C10d backend in PyTorch 1.0. Mixed precision training support through APEX (trains faster with less GPU memory on NVIDIA Tensor Cores). Extensible components that allows easy creation of new models and tasks.

For quite some time now, we know about the benefits of transfer learning in Computer Vision (CV) applications. Nowadays, pre-trained Deep Convolution Neural Networks (DCNNs) are the first go-to pre-solutions to learn a new task. These large models are trained on huge supervised corpora, like the ImageNet. And most important, their features are known to adapt well to new problems. This is particularly interesting when annotated training data is scarce. In situations like this, we take the models’ pre-trained weights, append a new classifier layer on top of it, and retrain the network. This is called transfer learning, and is one of the most used techniques in CV. Aside from a few tricks when performing fine-tuning (if the case), it has been shown (many times) that if training for a new task, models initialized with pre-trained weights tend to learn faster and be more accurate then training from scratch using random initialization.

A GWT-like python wrapper for Yahoo's YUI libraries. Write python code, make YUI objects.

When I first found FastAPI, I got it immediately. I was excited to find something so innovative and ergonomic built on Pydantic. Virtually every Agent Framework and LLM library in Python uses Pydantic, but when we began to use LLMs in Pydantic Logfire, I couldn't find anything that gave me the same feeling. PydanticAI is a Python Agent Framework designed to make it less painful to build production-grade applications with Generative AI. Built by the team behind Pydantic (the validation layer of the OpenAI SDK, the Anthropic SDK, LangChain, LlamaIndex, AutoGPT, Transformers, CrewAI, Instructor, and many more).

This project is a complete cross-platform (Windows, Linux) framework for Evolutionary Computation in pure python. See the project site at http://pyevolve.sourceforge.net or the blog at http://pyevolve.sourceforge.net/wordpress

This is an implementation of the Model-View-Controller (MVC) and the Observer patterns for the PyGTK2 graphic toolkit. See the project Homepage for further information.
