Installation

  • You will need:
    • the tensorflow non-gpu installation pre-requisites
    • an OpenCL 1.2-enabled GPU, and OpenCL 1.2-enabled drivers (check that clinfo shows your GPU, and that is shows as a GPU device)
    • python 3

For Ubuntu 16.04 and Mac Sierra, there are pre-built wheels available:

Simply download, unzip, then install using pip:

pip install --upgrade tensorflow-0.11.0rc0-py3-none-any.whl

For other operating systems, please build from source

By default, Tensorflow-cl will run using the first GPU available on your system. You can use the environment variable CL_GPUOFFSET to choose others:

  • export CL_GPUOFFSET=1 chooses the second GPU (ie, index 1)
  • export CL_GPUOFFSET=2 chooses the third GPU
