当我构建我的pip包时，我按照说明使用优化in this post构建除了例外，我没有gpu，所以我没有用cuda构建。所以它看起来像这样：
$ bazel build -c opt --copt=-mavx --copt=-mavx2 --copt=-mfma --copt=-mfpmath=both
--copt=-msse4.2 -k //tensorflow/tools/pip_package:build_pip_package
然后我按照说明在this question更新了我的pip包。当我试图再次运行我的代码时，我仍然得到以下警告。我在这里做错了什么想法？我错过了一步吗？

当我跑步时，我也很担心：
$ bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg/
我收到以下警告：

更新：我在不在pip环境中时运行了代码（没有运行$ source bin/activate），而且当我这样做时我没有收到错误。
