OS X上的Tensorflow导入错误

Question

TL;尝试在El Capitan上使用TensorFlow时DR获取ImportError: cannot import name pywrap_tensorflow 。

详情：我遵循here的Mac OS X的TensorFlow安装说明。

的Mac OS X，CPU只，Python 2.7版：

$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/tensorflow-0.9.0rc0-py2-none-any.whl 

$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/tensorflow-0.9.0rc0-py2-none-any.whl 

$ sudo pip install --upgrade $TF_BINARY_URL 

这些步骤是成功的。

所以让我们尝试一下：

22:54:00/tensorflow $ipython 
Python 2.7.11 (default, Jan 22 2016, 08:29:18)

Answer 1

TL; DR：当你想import tensorflow不要从TensorFlow git仓库的根目录运行ipython（或python）。

我回答了类似的问题here。最简单的解决方案是在运行ipython之前从当前目录（例如cd ~）中取出cd。这将防止Python被当前路径中的tensorflow源子目录所迷惑。 git存储库中的./tensorflow目录不包含运行TensorFlow所需的所有生成的代码（例如pywrap_tensorflow），但包含名为__init__.py的文件，这会使Python解释器混淆。
