    `CUDA_ERROR_ILLEGAL_ADDRESS` failures.

    A fix in CUDA 9.1.121 is expected in late February 2018. We do not expect a
    fix for CUDA 9.0.x. Until the fix is available, the only workaround is to

    or disable XLA:GPU.

    TensorFlow will print a warning if you use XLA:GPU with a known-bad version

    * To downgrade the cluster to version that does not support scale-to-zero feature:
    * 1. make sure there are no hpa objects with minReplicas=0. Here is a oneliner to update it to 1:
