Installing tensorflow ( 1.13.0_rc0 in this instance) gives the following output: WARNING: --batch mode is deprecated. Please instead explicitly shut down your Bazel server using the command "bazel shutdown". INFO: Invocation ID: 2ecbe79a-ba1d-4bee-8fc2-036289111298 You have bazel 0.22.0- (@non-git) installed. Please downgrade your bazel installation to version 0.21.0 or lower to build TensorFlow! for ~amd64 at least, the default is to use bazel 0.22.0 (0.20.0 is stable) An easy enough solution, just to implement it into the ebuild
I can confirm the bug and the solution (i.e. downgrade) on default/linux/amd64/17.1/no-multilib/hardened.
This should be fixed in 1.13.0_rc2 :)
