最近在看tensorflow 移動端部署，需要編譯源碼才支持，所以又拾起來了編譯這項老工作，其中遇到問題：
bazel build --cxxopt="-D_GLIBCXX_USE_CXX11_ABI=0" --config=opt --config=cuda //tensorflow/tools/pip_package:build_pip_package
WARNING: The following configs were expanded more than once: [cuda]. For repeatable flags, repeats are counted twice and may lead to unexpected behavior.

我一直搜索：ERROR: Skipping '//tensorflow/tools/pip_package:build_pip_package': error loading package 'tensorflow/tools/pip_package': E，說是
將bazel 回滾到0.52版本就可以，但是在./config階段，其要求bazel 版本是需要0.10.0或以上的，因此不是這個問題，然后關注第二個error：
Cuda Configuration Error: Cannot find libdevice.10.bc under /usr/local/cuda-8.0
執行下面兩個命令就可以了。
sudo cp /usr/local/cuda-8.0/nvvm/libdevice/libdevice.compute_50.10.bc /usr/local/cuda-8.0/nvvm/libdevice/libdevice.10.bc
sudo cp /usr/local/cuda-8.0/nvvm/libdevice/libdevice.10.bc /usr/local/cuda-8.0/libdevice.10.bc
然后，就可以了。
附：
卸載tensrofiow ：sudo pip uninstall tensorflow or sudo pip uninstall tensorflow-gpu
pip 問題：
Traceback (most recent call last):
File "/usr/local/bin/pip", line 7, in <module>
from pip._internal import main
ImportError: No module named _internal
from pip._internal import main 改為 from pip import main
（如果是no main 則相反from pip import main 改為 from pip._internal import main，是pip升級的問題）
