Ubuntu+GPU上Debug Torch项目fairseq

1，下载并启动zbstudio

$ git clone https://github.com/soumith/zbs-torch.git  
$ cd zbs-torch  
$ ./zbstudio.sh  

2，安装Torch
http://torch.ch/docs/getting-started.html

3，安装nccl

git clone https://github.com/NVIDIA/nccl
cd nccl
make install
sudo ldconfig
luarocks install nccl

找到libnccl.so*的目录在/etc/bashrc里加上：

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda-8.0/lib64:/usr/local/lib"

4，把fairseq导入zbstudio
在zbstudio里选择project->project directory->choose

5，preprocess数据

6，开始Debug
在train.lua里修改datadir参数指向fairseq/data-bin/iwslt14.tokenized.de-en
运行train.lua，也选中train.lua就是点那个绿色三角
