TensorFlow 未正确安装

Question

我是初学者，我尝试按照网站上的说明在 Macbook 上安装张量流。

sudo easy_install pip
sudo easy_install --upgrade six
sudo pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.6.0-py2-none-any.whl

安装后，当我尝试导入张量流时，出现以下错误：

    >>> import tensorflow
RuntimeError: module compiled against API version a but this version of numpy is 9
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/tensorflow/__init__.py", line 23, in <module>

    _pywrap_tensorflow = swig_import_helper()
  File "/Library/Python/2.7/site-packages/tensorflow/python/pywrap_tensorflow.py", line 24, in swig_import_helper
    _mod = imp.load_module('_pywrap_tensorflow', fp, pathname, description)
ImportError: numpy.core.multiarray failed to import
>>> 

我是 python 新手，我在互联网上尝试了一些解决方案，但到目前为止都没有奏效。也许错误是由于 pip 安装造成的。自两天以来，我一直坚持这一点。感谢您的帮助！

Answer 1

要补充上一个答案 - 在我的 OSX 机器 (10.11) 上，我发现了两个 numpy 的工厂安装 - 一个在 /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy，另一个在 /Library/Python/2.7/site-packages/numpy/。据我所知，pip 将升级 /Library 中的那个，但 python 一直尝试首先使用 /System/Library/ 中的那个。

作为临时解决方案，我只是将/System/Library 中的numpy 文件夹重命名为numpy.old。 Tensorflow 之后正确导入。

Answer 2

我想我遇到了同样的问题。这是由 Max OSX 上工厂安装的 Python 上的早期版本的工厂包含的 numpy 引起的。

我试过 sudo pip uninstall numpy 并且包含因子的 numpy 仍然存在。为了解决这个问题，我使用easy_install 升级了工厂包含的numpy，然后使用pip 安装tensorflow 并且它起作用了：

sudo easy_install -U numpy
sudo pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.6.0-py2-none-any.whl

Answer 3

所以最后我所做的是删除了 tensorflow、pip 和所有内容。问题是我使用的是 Mac OSX python，因此我遇到了问题。我使用 homebrew 安装 python，然后创建 virtualenv 并使用 pip 再次安装 tensorflow。之后它就开始工作了。

Answer 4

总结

这解决了我的问题：

$ sudo rm -rf /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy

环境和症状

我的 Mac OS X Yosemite 上安装了 3 个 python：

• 操作系统自带的2.6
• 我已经安装的2.7
• 3.4我已经安装了

当然，我在正确设置方面做得很差，python 二进制文件和库在 mac 上到处都是。

我在尝试使用 https://github.com/Ning-Ding/Implementation-CVPR2015-CNN-for-ReID/tree/master/CUHK03 时遇到此错误

$ python ./main.py --dataset cuhk-03.h5

查看 se7en007 对 https://github.com/tensorflow/tensorflow/issues/559 的评论后，我运行了这些喜欢我的问题的命令。查看numpy 版本中的差异以及rm 命令前后的路径。
