host and k8-opt folders in bazel-out

[t kevin]

Hi folks

I'm encountering a linking problem when building a customized tensorflow.

"_pywrap_tensorflow_internal.so" reports a missing symbol.

after a little digging i found there are 2 "_pywrap_tensorflow_internal.so"

bazel-out$ find ./ -name "_pywrap_tensorflow_internal.so" -type f
./host/bin/tensorflow/python/_pywrap_tensorflow_internal.so
./k8-opt/bin/tensorflow/python/_pywrap_tensorflow_internal.so

The symbol I added only exist in k8-opt nut not in host.

My question is what's the purpose of "host" and "k8-opt" folder and what's the difference between them.

Thanks a million

Kevin
