From the Wikipedia article on Torch <https://en.wikipedia.org/wiki/Torch_(machine_learning)>: Torch is an open-source machine learning library, a scientific computing framework, and a script language based on the Lua programming language. It provides a wide range of algorithms for deep learning, and uses the scripting language LuaJIT <https://en.wikipedia.org/wiki/LuaJIT>, and an underlying C implementation. It was created at IDIAP at EPFL. As of 2018, Torch is no longer in active development. However PyTorch <https://en.wikipedia.org/wiki/PyTorch>, which is based on the Torch library, is actively developed as of June 2021. PyTorch has language bindings for Python and for C++. I read that there is information available on calling C++ functions from Lua, but I don't know how easy that is, given the reliance of C++ on mangling names. There's also SciLua <https://scilua.org>, which I read is most easily installed with the ULua distribution of LuaJIT <https://ulua.io>. I'm not sure that falling back on a specific distribution of a minority implementation of Lua promises greater ease than pursuing a minority implementation of Python, alas. More on Torch below. >From Torch | Scientific computing for LuaJIT. <http://torch.ch/>: Torch is a scientific computing framework with wide support for machine learning algorithms that puts GPUs first. It is easy to use and efficient, thanks to an easy and fast scripting language, LuaJIT, and an underlying C/CUDA implementation. A summary of core features: - a powerful N-dimensional array - lots of routines for indexing, slicing, transposing, … - amazing interface to C, via LuaJIT - linear algebra routines - neural network, and energy-based models - numeric optimization routines - Fast and efficient GPU support - Embeddable, with ports to iOS and Android backends >From Lua and Torch - Artificial Inteligence - GitBook <https://leonardoaraujosantos.gitbook.io/artificial-inteligence/appendix/lua> : Torch is a scientific computing framework based on Lua with CPU and GPU backends. You can imagine like a Numpy but with CPU and GPU implementation. Some nice features: - Efficient linear algebra functions with GPU support - Neural Network package, with automatic differentiation (No need to backpropagate manually) - Multi-GPU support Lua Torch :: Anaconda.org <https://anaconda.org/alexbw/lua-torch> Get Lua running with Torch on Windows 10 with limited Admin rights - Stack Overflow <https://stackoverflow.com/questions/48277220/get-lua-running-with-torch-on-windows-10-with-limited-admin-rights> Lua & Torch Tutorial - luckylwk.github.io <http://luckylwk.github.io/2015/05/23/lua-torch/> -- You received this message because you are subscribed to the Google Groups "leo-editor" group.
