Torch Installation

This is the suggested way to install the dependencies on Ubuntu 14.04+:

  • NVIDIA CUDA 7.0+
  • NVIDIA cuDNN v4
  • Torch
  • ImageNet dataset

Requirements

  • NVIDIA GPU with compute capability 3.5 or above

Install CUDA

  1. Install the build-essential package:
sudo apt-get install build-essential
  1. If you are using a Virtual Machine (like Amazon EC2 instances), install:
sudo apt-get update
sudo apt-get install linux-generic

  1. Download the CUDA .deb file for Linux Ubuntu 14.04 64-bit from: https://developer.nvidia.com/cuda-downloads. The file will be named something like cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb

  2. Install CUDA from the .deb file:

sudo dpkg -i cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb
sudo apt-get update
sudo apt-get install cuda
echo "export PATH=/usr/local/cuda/bin/:\$PATH; export LD_LIBRARY_PATH=/usr/local/cuda/lib64/:\$LD_LIBRARY_PATH; " >>~/.bashrc && source ~/.bashrc
  1. Restart your computer

Install cuDNN v4

  1. Download cuDNN v4 from https://developer.nvidia.com/cuDNN (requires registration). The file will be named something like cudnn-7.0-linux-x64-v4.0-rc.tgz.

  2. Extract the file to /usr/local/cuda:

tar -xvf cudnn-7.0-linux-x64-v4.0-rc.tgz
sudo cp cuda/include/*.h /usr/local/cuda/include
sudo cp cuda/lib64/*.so* /usr/local/cuda/lib64

Install Torch

  1. Install the Torch dependencies:
curl -sk https://raw.githubusercontent.com/torch/ezinstall/master/install-deps | bash -e
  1. Install Torch in a local folder:
git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch; ./install.sh

If you want to uninstall torch, you can use the command: rm -rf ~/torch

Install the Torch cuDNN v4 bindings

git clone -b R4 https://github.com/soumith/cudnn.torch.git
cd cudnn.torch; luarocks make
