tensorflow: error: namespace "Eigen::half_impl" has no member "__half_raw" when building latest TensorFlow/CUDA 9.0

When trying to build latest TensorFlow for CUDA 9.0/CuDNN 7.0, from today’s head

Complete instructions to reproduce are here, but basically I followed steps in in Dockerfile.devel-gpu to install dependencies, and then did bazel build -c opt --config=cuda

Here are the errors
