How to use TensorFlow with AMD GPU’s

Most machine learning frameworks that run with a GPU support Nvidia GPUs, but if you own a AMD GPU you are out of luck.

Recently AMD has made some progress with their ROCm platform for GPU computing and does now provide a TensorFlow build for their gpus.

Since I work with tensorflow and own a AMD GPU it was time to give it a try. I stumpled upon these instructions for TensorFlow 1.8 but since they are outdated, I decided to write down what I did.

1. Set up Linux

It looks like there is currently no ROCm support for Windows. And no, WSL aka Bash for Windows does not work. But there are packages for CentOS/RHEL 7 and Ubuntu. I used Ubuntu 18.04.

2. Install ROCm

Just follow the ROCm install instructions.

3. Install TensorFlow

AMD provides a special build of TensorFlow. Currently they support TensorFlow 1.12.0. You can build it yourself, but the most convenient way to use it, is to install the package from PyPI:

sudo apt install python3-pip 
pip3 install --user tensorflow-rocm

4. Train a Model

To test your setup you can run the image recognition task from the Tensorflow tutorials.

git clone https://github.com/tensorflow/models.git
cd models/tutorials/image/imagenet
python3 classify_image.py

and the result should look like this:

giant panda, panda, panda bear, coon bear, Ailuropoda melanoleuca (score = 0.89103)
indri, indris, Indri indri, Indri brevicaudatus (score = 0.00810)
lesser panda, red panda, panda, bear cat, cat bear, Ailurus fulgens (score = 0.00258)
custard apple (score = 0.00149)
earthstar (score = 0.00141)

Extra: Monitor your GPU

If you like to check that your model fully utilize your GPU, you can use the (radeontop)[https://github.com/clbr/radeontop] tool:

Install it with

sudo apt-get install radeontop

and run it

sudo radeontop

This will dump the statistics to the command line.

sudo radeontop -d -
