Experimenting with even easier Torch installation

[Alex W]

Hello,

I've been packaging up LuaJIT and Torch packages for even easier install using Continuum.IO's "conda" tool (http://conda.pydata.org/).

The goal is to turn all of the LuaJIT numerical libraries into reliable, fast, architecture-independent, one-line installs.

Here's how you can, from scratch, get all the packages you need to train a basic neural net on the CPU.

First, install anaconda, if you don't have it (you can check by typing "conda help", and if nothing useful comes up, then try the lines below)

# Install Anaconda on Linux:

wget http://repo.continuum.io/miniconda/Miniconda-latest-Linux-x86_64.sh

bash Miniconda-latest-Linux-x86_64.sh -b -p $HOME/anaconda

# Install Anaconda on OS X

wget http://repo.continuum.io/miniconda/Miniconda-latest-MacOSX-x86_64.sh

bash Miniconda-latest-MacOSX-x86_64.sh -b -p $HOME/anaconda

# Then, to install all the packages you need for training a neural network on the CPU, type:

conda install -c alexbw lua-nn lua-trepl lua-optim # That's it!

I'm just at the beginning stages of this, so please let me know if there's hiccups, and I'll try to work through it. 

You can look at all the build recipes here:

And if you want to submit a pull request for a new package (please do!), here's a walk-through explanation of how these recipes work:

Hi Alex,

I see that miniconda is available for windows as well. Does this mean torch on windows ?

I haven't done any work on Windows yet. I would be delighted to help anyone who would like to try, though.

I've been working on this very slowly, but it now works. Install with the following-command.

conda install lua=5.2 lua-science -c alexbw

Options for lua= are lua=2.0, lua=5.1, lua=5.2, lua=5.3.

OSX/Linux only. CUDA not built for Linux yet, but working on that. +1 the CUDA issue on the github repo to indicate desire.

Hi A,

I am really interested in your work and would like to help too. Right now the two painful package installation is cutorch and cunn. 

Please let me know if there is any easy way to do it. 

Cheers, 

Zhong
