Getting this error while building sci-libs/tensorflow-1.14.0-r1. I guess https://github.com/bazelbuild/bazel/issues/7899 suggests some things to add to the ebuild. emerge seems to have deleted the build log then choked on tensorflow_estimator, but the important part is here: ERROR: /var/tmp/portage/sci-libs/tensorflow-1.14.0-r1/work/tensorflow-1.14.0-python2_7/tensorflow/core/BUILD:2750:1: Executing genrule //tensorflow/core:version_info_gen failed (Exit 1): bash failed: error executing command (cd /var/tmp/portage/sci-libs/tensorflow-1.14.0-r1/work/tensorflow-1.14.0-python2_7-bazel-base/execroot/org_tensorflow && \ exec env - \ PATH=/var/tmp/portage/sci-libs/tensorflow-1.14.0-r1/temp/python2.7/bin:/var/tmp/portage/sci-libs/tensorflow-1.14.0-r1/temp/python3.6/bin:/usr/lib/portage/python3.6/ebuild-helpers/xattr:/usr/lib/portage/python3.6/ebuild-helpers:/usr/lib/llvm/8/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/opt/nvidia-cg-toolkit/bin:/opt/eagle/bin:/opt/cuda/bin \ /bin/bash -c 'source external/bazel_tools/tools/genrule/genrule-setup.sh; bazel-out/host/bin/tensorflow/tools/git/gen_git_source --generate external/local_config_git/gen/spec.json external/local_config_git/gen/head external/local_config_git/gen/branch_ref "bazel-out/host/bin/tensorflow/core/util/version_info.cc" --git_tag_override=${GIT_TAG_OVERRIDE:-}') Execution platform: @bazel_tools//platforms:host_platform Error occurred while attempting to use the default Python toolchain (@bazel_tools//tools/python:autodetecting_toolchain). Could not get interpreter version via '/var/tmp/portage/sci-libs/tensorflow-1.14.0-r1/temp/python2.7/bin/python3 -V' ---------------- Note: The failure of target //tensorflow/tools/git:gen_git_source (with exit code 1) may have been caused by the fact that it is a Python 2 program that was built in the host configuration, which uses Python 3. You can change the host configuration (for the entire build) to instead use Python 2 by setting --host_force_python=PY2. If this error started occurring in Bazel 0.27 and later, it may be because the Python toolchain now enforces that targets analyzed as PY2 and PY3 run under a Python 2 and Python 3 interpreter, respectively. See https://github.com/bazelbuild/bazel/issues/7899 for more information. ---------------- Portage info: $ emerge -pqv '=sci-libs/tensorflow-1.14.0-r1::gentoo' [ebuild U ]

I got the same error and then downgraded to bazel-0.26.1-r1 which resolved it for me. What a monstrous package to emerge though! # du -skh /var/tmp/portage/sci-libs/tensorflow-1.14.0-r2/ 21G /var/tmp/portage/sci-libs/tensorflow-1.14.0-r2/ # genlop -t tensorflow | tail -n 3 Sat Aug 31 03:57:48 2019 >>> sci-libs/tensorflow-1.14.0-r2 merge time: 5 hours, 55 minutes and 18 seconds.
Downgrading bazel fixed it for me, thanks @altrent. I guess ~tensorflow-1.14 should block >=bazel-0.27 ? That would resolve the bug for now, if not the root cause..
I've dropped tf-1.14 from the tree, please file a new bug/reopen if this still happens :)
