However, many AMD GPUs support OpenCL and Metal. See this hardware compatibility list for more information. To support GPU-backed ML code using Keras, we can leverage PlaidML. Below are the steps to install TensorFlow, Keras, and PlaidML, and to test and benchmark GPU support. These instructions assume a fresh install of macOS 10.15 Catalina using the system python installation.
