## Updated 06 Oct 2003 Maximum Entropy Modeling Toolkit

 Pop 39.8 62.06

The Maximum Entropy Toolkit provides a set of tools and library for constructing maximum entropy (maxent) models in either Python or C++. It features conditional maximum entropy models, L-BFGS and GIS parameter estimation, Gaussian Prior smoothing, a C++ API, a Python extension module, a command line utility, and good documentation.

## Updated 19 Apr 2007 latexmath2png

 Pop 19.9 50.61

latexmath2png is a versatile program and Python module to allow conversion of LaTeX math equations to PNG images. It currently supports generating equations in the standard \$...\$ LaTeX math environment style.

## Updated 17 May 2009 PyGTS

 Pop 27.77 42.5

PyGTS is a Python package that can be used to construct, manipulate, and perform computations on 3D triangulated surfaces. It is a hand-crafted and pythonic binding for the GNU Triangulated Surface (GTS) Library.

## Updated 09 Jun 2012 hmm

 Pop 40.32 5.72

hmm is a Python module designed to work with Hidden Markov Models. The usual algorithms (Viterbi, Baum-Welsh) are implemented using Numeric Python.

## Updated 09 Jun 2012 RPy

 Pop 60.12 5.69

RPy is a very simple, yet robust, Python interface to the R Programming Language. It can manage all kinds of R objects and can execute arbitrary R functions (including the graphic functions). All the errors from the R language are converted to Python exceptions. Any module that later were installed on the R system can easily be used from within Python, without introducing any changes.

## Updated 14 Dec 2009 Virtual Ideal Functionality Framework

 Pop 40.82 3.87

Virtual Ideal Functionality Framework is a framework for creating efficient and secure multi-party computations (SMPC). Players, who do not trust each other, participate in a joint computation based on their private inputs. The computation is done using a cryptographic protocol which allows them to obtain a correct answer without revealing their inputs. Operations supported include addition, multiplication, and comparison, all with Shamir secret shared outputs.

## Updated 13 Sep 2005 MayaVi

 Pop 142.65 3.76

MayaVi is a free, cross platform, easy-to-use scientific data visualizer. It provides a powerful GUI to ease the visualization process. It is written in Python and uses the Visualization Toolkit (VTK) for the graphics. MayaVi can be scripted from other Python programs and also from the interactive Python interpreter. MayaVi includes the VTK Pipeline browser. The VTK Pipeline browser is a Python module (vtkPipeline) that enables one to view and configure the objects in the VTK pipeline graphically with a Tkinter-based GUI. The browser should work for any Python script that uses VTK. MayaVi also provides classes to pickle a VTK object and a simple class documentation browser.

## Updated 16 Jul 2009 Hasard

 Pop 47.15 3.13

Hasard is a pseudo-random number generator (PRNG) library. It includes multiple engines (algorithms): Park-Miller, Mersenne Twister, Linux device (/dev/urandom or /dev/random), and more. It has a simple but powerful API. For example, a PRNG seed can be generated using strong entropy (using a hardware random number generator like /dev/random on Linux). The library is written in C, and a Python binding is available. The word "hasard" is the French word for "randomness" or "chance".

## Updated 13 Apr 2008 Simple Python Fixed-Point Module

 Pop 47.85 2.19

SPFPM (Simple Python Fixed-Point Module) is a Python module which provides basic facilities for manipulating (binary) fixed-point numbers. The number of fractional binary digits is tunable, allowing near-arbitrary precision arithmetic. Arithmetic and mathematical functions such as sqrt, exp, log, sin, and cos are available.

## Updated 01 Apr 2012 The Python audio processing suite

 Pop 33.11 2.01

The Python audio processing suite is a module that contains a variety of convenience functions to process audio signals. It can be used to plot spectral analyses of a song across time and to quickly ascertain encoding quality, but the instrumental goal of this suite is to robustly identify duplicated songs, regardless of which album they were released in, encoding quality, or start time.
