Torch7 Library.

Torch7 provides a Matlab-like environment for state-of-the-art machine learning algorithms. It is easy to use and provides a very efficient implementation, thanks to an easy and fast scripting language (Lua) and a underlying C implementation.

In order to install Torch7 you can follow these simple instructions, but we suggest reading the detailed manual at http://www.torch.ch/manual/install/index

Requirements

• C/C++ compiler
• cmake
• gnuplot
• git

Optional

• Readline
• QT (QT4.8 is now supported)
• CBLAS
• LAPACK

Installation

$ git clone git://github.com/andresy/torch.git
$ cd torch
$ mkdir build
$ cd build

$ cmake .. 
OR
$ cmake .. -DCMAKE_INSTALL_PREFIX=/my/install/path

$make install

Running

3rd Party Packages

Torch7 comes with a package manager based on Luarocks. With it it's easy to install new packages:

$ torch-rocks install image
$ torch-rocks list
$ torch-rocks search --all

Impossible to install on OS X 10.9

I'm unable to install sundown-ffi on my Mac (OS X 10.9). Any idea of what's happening here?

BUG: ascii.lua:318: cannot convert 'nil' to 'int'

Hi, I'm writting test scripts for debian package lua-torch-sundown, and by chance I found this bug.

Shell code snippet:

echo 'level 3'
luajit -e "sundown = require 'sundown'; sundown.renderASCII[[
THIS IS TITLE
===

# H1

* item 1  
* item 2  
* item 3  

## H2

1. item 1  
2. item 2  
3. item 3  

### H3

\`\`\`
shell> this is some code example
\`\`\`

#### H4

and lets see if \`split line\` works

---

this is _style1_

this is *style2_

Sundown.renderASCII seems to be working.
]]"

result:

level 3

Bug in ``` indentation

When there is ``` code, only the first line has an additional white space.
The following lines are totally left-oriented without margin (see below).

Tensors of different types

Actually, several types of Tensor exists:
 ByteTensor -- contains unsigned chars
CharTensor -- contains signed chars
ShortTensor -- contains shorts
IntTensor -- contains ints
FloatTensor -- contains floats
DoubleTensor -- contains doubles 

In my opinion all code within ``` should have 3 spaces of indentation and a '\n' at the beginning.

Options in ascii.lua is either undefined nil or a global variable
