libtorch3-dev 3.1-2.1build1 (amd64 binary) in ubuntu xenial

 Torch is a machine-learning library, written in C++. Its aim is to
 provide the state-of-the-art of the best algorithms.
 .
  * Many gradient-based methods, including multi-layered perceptrons,
    radial basis functions, and mixtures of experts. Many small "modules"
    (Linear module, Tanh module, SoftMax module, ...) can be plugged
    together.
  * Support Vector Machine, for classification and regression.
  * Distribution package, includes Kmeans, Gaussian Mixture Models,
    Hidden Markov Models, and Bayes Classifier, and classes for speech
    recognition with embedded training.
  * Ensemble models such as Bagging and Adaboost.
  * Non-parametric models such as K-nearest-neighbors, Parzen Regression
    and Parzen Density Estimator.
 .
 This package is the Torch development package (header files and
 static library.)
