Compiling Torch 7

[Hanqi Sun]

Hi,

I just installed Torch 7 in my home directory. I had some troubles but
managed to install it successfully. So I want to share my experience here.

0. Going to http://torch.ch/docs/getting-started.html
1. Run git clone https://github.com/torch/distro.git ~/torch --recursive
2. Skip the second line and directly run cd ~/torch; ~/torch/install.sh as
we already have all the packages.
3. After it finishes, run source ~/.bashrc (and maybe source ~/.bash_profile
)
4. Now torch should be ready to use by typing th.You can also try
~/torch/test.sh
to run the unit tests. On GPU2, it failed a few tests for me due to out of
memory and precision but I can run some Torch codes with no problem.

If you have questions or comments please do not hesitate to contact me.

Best,
Hanqi
