Torch的安装

I.安装torch

参考官网给的教程：http://torch.ch/docs/getting-started.html

# in a terminal, run the commands WITHOUT sudo
git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch; bash install-deps;
sudo ./install.sh

如果是linux操作系统执行

source ~/.bashrc

如果是linux操作系统，zsh终端执行

source  ~/.zshrc

#如果是OSX苹果

source ~/.profile

如果想安装Lua-5.2版本的torch,可以执行如下操作

cd ~/torch


# clean old torch installation

./clean.sh

# optional clean command (for older torch versions)
# curl -s https://raw.githubusercontent.com/torch/ezinstall/master/clean-old.sh | bash
# https://github.com/torch/distro : set env to use lua
TORCH_LUA_VERSION=LUA52 ./install.sh

如果想要删除torch，可以执行如下操作

rm -rf ~/torch

II.运行torch
