У меня возникла проблема при установке cutorch с luarocks. Ошибка сообщает, что архитектура графического процессора «compute_61» не поддерживается. После некоторого поиска я понял, что проблема может быть вызвана старой версией CUDA. Но это не так, так как у меня CUDA 8.0
sudo ~/torch/install/bin/luarocks install cutorch
