matio 出现的详细错误及解决
错误：
/root/torch/install/bin/luajit: /root/torch/install/share/lua/5.1/trepl/init.lua:389: /root/torch/install/share/lua/5.1/trepl/init.lua:389: /root/torch/install/share/lua/5.1/trepl/init.lua:389: /root/torch/install/share/lua/5.1/matio/ffi.lua:24: Could not find libmatio. Please make sure that you installd MatIO and you have the shared libraries (libmatio.so or libmatio.dylib) in your library path
解决方案：
sudo apt-get install libmatio2
luarocks install matio
nccl
采用 multi-GPUs 训练时速度更高：
git clone https://github.com/NVIDIA/nccl.git
cd nccl
make
make install
luarocks install nccl
