Torch (easy) install

This is just an easy install script for Torch7.

The goal of this script is to enable one line installs. To install Torch on any machine, just do:

curl -s https://raw.githubusercontent.com/torch/ezinstall/master/install-all | bash

Once installed, you should be able to run Torch with basic libraries:

luajit -ltorch
# or, using our improved LuaJIT interpreter:
th -lparallel -loptim -lpl -limage

This script has been tested on MacOS X 10.8, and Ubuntu 12.04. It should work on earlier Ubuntus and MacOS Xs, but other platforms are not supported.

On Ubuntu you'll need 'sudo' privileges, as the default install is global, and the script needs to install dependencies.

If you've already installed the dependencies, and don't have root privileges, you can use this command to just install Torch:

curl -s https://raw.githubusercontent.com/torch/ezinstall/master/install-luajit+torch | bash

By default, it will install Torch in /usr/local/ , you can override this default path by doing:

curl -s https://raw.githubusercontent.com/torch/ezinstall/master/install-luajit+torch | PREFIX=~/local bash

We install Luarocks along with LuaJIT and Torch, so you can easily install new packages:

luarocks search lua-cjson
luarocks install lua-cjson

By default, luarocks includes a link to our own Rocks repository, hosted here. If you wish to publish your packages as rocks for Torch, simply clone this repo, add your rocks, and make a pull request on Github!

Updating from a previous version

Note that if you are coming from a previous version you are advise to clean up the old installation with the following command

curl -s https://raw.githubusercontent.com/torch/ezinstall/master/clean-old.sh | bash
