创建 pip 包并安装

$ bazel build -c opt //tensorflow/tools/pip_package:build_pip_package

$ bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg

# .whl 文件的实际名字与你所使用的平台有关
$ pip install /tmp/tensorflow_pkg/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

GPU 相关问题

如果在尝试运行一个 TensorFlow 程序时出现以下错误:

ImportError: libcudart.so.7.0: cannot open shared object file: No such file or directory

请确认你正确安装了 GPU 支持

在 Linux 上

如果出现错误:

...
 "__add__", "__radd__",
             ^
SyntaxError: invalid syntax

解决方案: 确认正在使用的 Python 版本为 Python 2.7.

在 Mac OS X 上

如果出现错误:

import six.moves.copyreg as copyreg
ImportError: No module named copyreg

1. 升级全系统的 six:

    sudo easy_install -U six

2. 通过 homebrew 安装一个隔离的 python 副本:

    brew install python

3. 在virtualenv 内编译或使用 TensorFlow.

如果出现错误:

>>> import tensorflow as tf
