Torch 安装过程

安装环境：

虚拟机+Ubuntu14.04

安装依赖：

curl -sk https://raw.githubusercontent.com/torch/ezinstall/master/install-deps| bash

安装LuaJIT, LuaRocks并LuaRocks安装Torch 和其他的包

git clone https://github.com/torch/distro.git ~/torch --recursive

cd ~/torch; ./install.sh

特别注意：在./install.sh时出现了错误

解决方法如下：

修改install.sh如下：

echo "Installing Lua version: ${TORCH_LUA_VERSION}"mkdir -p installmkdir -p buildcd buildcmake .. -DCMAKE_INSTALL_PREFIX="${PREFIX}" -DCMAKE_BUILD_TYPE=Release -DWITH_${TORCH_LUA_VERSION}=OFF 2>&1 >>$PREFIX/install.log || exit 1(make 2>&1 >>$PREFIX/install.log  || exit 1) && (make install 2>&1 >>$PREFIX/install.log || exit 1)cd ..

即将

-DWITH_${TORCH_LUA_VERSION}=ON 修改为OFF
