Tensorflow

TensorFlow is an open source library for deep learning.

Installation instructions

Virtualenv method

Detailed instructions are provided on the TensorFlow website.

1. Install CUDA
   1. Download CUDA from the nVidia site (CUDA toolkit 7.5):

      wget http://developer.download.nvidia.com/compute/cuda/7.5/Prod/local_installers/cuda-repo-ubuntu1504-7-5-local_7.5-18_amd64.deb

   2. Update root path (if necessary):

      sudo nano /root/.bashrc

      export PATH=$PATH:/usr/local/sbin:/usr/sbin:/sbin:/opt/conda/bin

   3. Install deb (c.f. instructions here):

      sudo -s

      dpkg -i cuda-repo-ubuntu1504-7-5-local_7.5-18_amd64.deb

      apt-get update

      aptitude install cuda

2. Set up environment

   1. nano ~/.bashrc

      # Add these lines to the end of your .bashrc file:

      export CUDA_HOME=/usr/local/cuda-7.5

      export LD_LIBRARY_PATH=${CUDA_HOME}/lib64

      PATH=${CUDA_HOME}/bin:${PATH}

      export PATH

3. Create Virtualenv:

   1. virtualenv --system-site-packages ~/tensorflow

4. Activate Virtualenv:

   1. source ~/tensorflow/bin/activate

      # Prompt should change to start with "(tensorflow)$"
