INSTALL.md

• Find a machine with Ubuntu 14.04+ and an NVIDIA GPU with compute capability 3.5 or above

Then, install everything that is needed by using the instructions below:

Install CUDA

sudo apt-get install build-essential

If you are using a Virtual Machine (like Amazon EC2 instances), install:

sudo apt-get update
sudo apt-get install linux-generic

Download the CUDA .deb file for Linux Ubuntu 14.04 64-bit from this page: https://developer.nvidia.com/cuda-downloads It would be a file named similar this: cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb Now, install it using:

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

Restart your computer

Install CuDNN

• Go to https://developer.nvidia.com/cuDNN and use the Download button (you have to register and login to download. no way around that.)
• Download cuDNN R3 for Linux. You will download a file cudnn-7.0-linux-x64-v3.0-prod.tgz then use the commands:

tar -xvf cudnn-7.0-linux-x64-v3.0-prod.tgz
sudo cp cuda/include/*.h /usr/local/cuda/include
sudo cp cuda/lib64/*.so* /usr/local/cuda/lib64

Install Torch Dependencies

curl -sk https://raw.githubusercontent.com/torch/ezinstall/master/install-deps | bash -e

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
