Does Google Tensorflow support OpenCL

Question

Does Google Tensorflow support OpenCL... or is it still only Cuda?

OpenCL does not appear to be supported yet (April 2017) per this open issue - https://github.com/tensorflow/tensorflow/issues/22 but I keep reading that support exists -- I might be missing something.

Answer 1

tf-coriander is an implementation of Tensorflow for OpenCL 1.2 GPUs. It's based on coriander, which is a general compiler to run NVIDIA® CUDA™ code on OpenCL 1.2 devices. Disclosure: I'm the author, of both projects.

Answer 2

There is OpenCL support via SYCL on Tensorflow, some features are in, others are in progress: https://github.com/tensorflow/tensorflow/issues/22#issuecomment-266050835
