我正在运行Ubuntu 16.04。我有一个运行深度神经网络的Docker容器，运行得很完美。但如果我指定使用CUDA，它会抛出以下错误：

/root/torch/install/bin/luajit: /root/torch/install/share/lua/5.1/trepl/init.lua:384: module 'cutorch' not found:No LuaRocks module found for cutorch    no field package.preload['cutorch']    no file '/root/.luarocks/share/lua/5.1/cutorch.lua'    no file '/root/.luarocks/share/lua/5.1/cutorch/init.lua'    no file '/root/torch/install/share/lua/5.1/cutorch.lua'    no file '/root/torch/install/share/lua/5.1/cutorch/init.lua'    no file './cutorch.lua'    no file '/root/torch/install/share/luajit-2.1.0-beta1/cutorch.lua'    no file '/usr/local/share/lua/5.1/cutorch.lua'    no file '/usr/local/share/lua/5.1/cutorch/init.lua'    no file '/root/.luarocks/lib/lua/5.1/cutorch.so'    no file '/root/torch/install/lib/lua/5.1/cutorch.so'    no file '/root/torch/install/lib/cutorch.so'    no file './cutorch.so'    no file '/usr/local/lib/lua/5.1/cutorch.so'    no file '/usr/local/lib/lua/5.1/loadall.so'stack traceback:    [C]: in function 'error'    /root/torch/install/share/lua/5.1/trepl/init.lua:384: in function 'require'    /root/openface/batch-represent/main.lua:22: in main chunk    [C]: in function 'dofile'    /root/torch/install/lib/luarocks/rocks/trepl/scm-1/bin/th:145: in main chunk    [C]: at 0x00406670

CUDA/NVIDIA驱动程序是否需要在Docker容器中单独安装？如果需要，如何安装？

我正在使用GTX Geforce TITAN黑卡。

回答：

已经解决了问题。我之前使用的Docker文件仅适用于在CPU上执行操作。

我应该创建另一个Docker文件，或者使用像Dl-docker或Nvidia-docker这样的工具。
