I am tring to use gdb to trace Tensorflow operation kernel implementation with Eigen SYCL support. However, when I try to install the .whl package, some error messages about fglrx pop up.

Error message

Compiling /tmp/pip-1vfYDJ-build/tensorflow-1.0.1.data/purelib/tensorflow/contrib/cudnn_rnn/ops/gen_cudnn_rnn_ops.py ...
  File "/tmp/pip-1vfYDJ-build/tensorflow-1.0.1.data/purelib/tensorflow/contrib/cudnn_rnn/ops/gen_cudnn_rnn_ops.py", line 1

The SYCL variant currently requires a platform that supports SPIR or SPIRV, like Intel or AMD. NVIDIA platform does not currently support neither.

You can't (currently) use SYCL with TensorFlow on Intel GPUs. However, it is coming soon. There are a few fixes you will need and then it will work correctly. You will need to wait for a new Intel OpenCL GPU driver and then for a few compatibility commits to TensorFlow before it will work on Intel GPU. You may also want to wait a little longer for some performance improvements, because we have been focusing more on correctness, first, with performance coming a little later.
