最近在看tensorflow 移动端部署，需要编译源码才支持，所以又拾起来了编译这项老工作，其中遇到问题：

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，说是

将bazel 回滚到0.52版本就可以，但是在./config阶段，其要求bazel 版本是需要0.10.0或以上的，因此不是这个问题，然后关注第二个error：

Cuda Configuration Error: Cannot find libdevice.10.bc under /usr/local/cuda-8.0

执行下面两个命令就可以了。

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：

    卸载tensrofiow ：sudo pip uninstall tensorflow or sudo pip uninstall tensorflow-gpu

pip 问题：

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 改为 from pip  import main 

（如果是no main 则相反from pip import main 改为 from pip._internal  import main，是pip升级的问题）
