loop or previous error loading module 'cutorch'

[mark dana]

Hi everyone!

I installed torch and GPU related dependencies by running the script:

```

apt-get update
apt-get -y install sudo
git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch; bash install-deps;
./install.sh
. /root/torch/install/bin/torch-activate
apt-get update
sudo apt-get -y install libmatio-dev
~/torch/install/bin/luarocks install --server=https://luarocks.org/dev matio
sudo apt -y install nvidia-cuda-toolkit
~/torch/install/bin/luarocks install --server=https://luarocks.org/dev cutorch
git clone https://github.com/torch/cunn
cd cunn
~/torch/install/bin/luarocks make rocks/cunn-scm-1.rockspec

```

However when I try `th testcuda.lua` where `testcuda.lua` is

```

require 'torch'
require 'nn'
require 'nngraph'
require 'optim'
ok, cunn = pcall(require, 'cunn')
ok2, cutorch = pcall(require, 'cutorch')
print(ok,cunn,ok2,cutorch)
cutorch.setDevice(1)

```

The error message is

```

`nvidia-smi` and `nvcc -V` all work well. Anyone knows how to solve it? Thanks a bunch to any possible help :)
