I'm trying to debug failure here.

It seems bazel fails at 2to3 on this file and also on this one. The 2to3 command returns Status 1, but doesn't print anything.

bazel-out/host/bin/external/bazel_tools/tools/python/2to3 --no-diffs --nobackups --write --output-dir bazel-out/local_linux-py3-opt/genfiles/python3/tensorflow/contrib/immediate/python/immediate/extra_tests --write-unchanged-files tensorflow/contrib/immediate/python/immediate/extra_tests/math_ops_test.py

Here are the full steps to reproduce, any suggestion how to debug?
