由于Numpy错误而无法使用tensorflow

问题描述

我正在运行Mac OS X Yosemite-10.10.5，我正在尝试在Python 2.7.10中运行tensorflow。 当我尝试导入tensorflow时出现此错误，我相信是由于未更新Numpy引起的：

$ python
Python 2.7.10 (default, Jul 14 2015, 19:46:27) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin

>>> import tensorflow as tf

_mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)
ImportError: numpy.core.multiarray failed to import

更新：当我尝试更新numpy时：

$ pip install numpy --upgrade
Collecting numpy

tensorflow 1.1.0 has requirement six>=1.10.0, but you'll have six 1.4.1 which is incompatible.
Installing collected packages: numpy
Found existing installation: numpy 1.8.0rc1
Cannot uninstall 'numpy'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

所以我想通了：

我切换到python3，安装了numpy和tensorflow：

Tensorflow install command:
python3 -m pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.0-py3-none-any.whl
Collecting tensorflow==0.12.0 from https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.0-py3-none-any.whl

并在Python和numpy和tensorflow中都进行了测试。
