1. 安裝 Torch

Torch 真的蠻好裝的，按照官網的文章裝就裝好了。

git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch; bash install-deps;
./install.sh

之後要跟 Digits 一起用的話，再參考這篇文章裝一些東西

sudo apt-get install --no-install-recommends libhdf5-serial-dev liblmdb-dev
luarocks install tds
luarocks install "https://raw.github.com/deepmind/torch-hdf5/master/hdf5-0-0.rockspec"
luarocks install "https://raw.github.com/Neopallium/lua-pb/master/lua-pb-scm-0.rockspec"
luarocks install lightningmdb 0.9.18.1-1 LMDB_INCDIR=/usr/include LMDB_LIBDIR=/usr/lib/x86_64-linux-gnu
luarocks install "https://raw.githubusercontent.com/ngimel/nccl.torch/master/nccl-scm-1.rockspec"

2. 安裝 PyTorch

PyTorch 就更好裝了，在官網選擇好之後就搞定了。

pip install http://download.pytorch.org/whl/cu80/torch-0.3.0.post4-cp27-cp27mu-linux_x86_64.whl
pip install torchvision
