python - tensorflow 导入错误。不包含/Library/Python/2.7/site-packages

Question

正在尝试安装 tensorflow。试过 anaconda，它有效但影响了我的其他程序。然后决定使用 pip install。

但是在我安装它之后，我无法在 ipython 中导入它。

消息如下:我尝试卸载并重新安装。

pip install tensorflow
Requirement already satisfied (use --upgrade to upgrade): tensorflow in /Library/Python/2.7/site-packages 
Cleaning up...

首先我尝试在 ipython 中导入:

In [1]: import tensorflow
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-a649b509054f> in <module>()
----> 1 import tensorflow

ImportError: No module named tensorflow

然后我将tensorflow的文件夹从/Library/Python/2.7/site-packages复制到/usr/local/lib/python2.7/site-packages/。我尝试导入:

In [1]: import tensorflow
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-a649b509054f> in <module>()
----> 1 import tensorflow

/Library/Python/2.7/site-packages/tensorflow/__init__.py in <module>()
     21 from __future__ import print_function
     22 
---> 23 from tensorflow.python import *
     24 
     25 

/Library/Python/2.7/site-packages/tensorflow/python/__init__.py in <module>()
     57 please exit the tensorflow source tree, and relaunch your python interpreter
     58 from there.""" % traceback.format_exc()
---> 59   raise ImportError(msg)
     60 
     61 from tensorflow.core.framework.node_def_pb2 import *

ImportError: Traceback (most recent call last):

    from tensorflow.core.framework.graph_pb2 import *
  File "tensorflow/core/framework/graph_pb2.py", line 6, in <module>
    from google.protobuf import descriptor as _descriptor
ImportError: No module named google.protobuf


Error importing tensorflow.  Unless you are using bazel,
you should not try to import tensorflow from its source directory;
please exit the tensorflow source tree, and relaunch your python interpreter
from there.

但是，我也在/Library/Python/2.7/site-packages 下安装了 protobuf。

我发现这个版本的 ipython 使用的是 macports python 包目录:/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/

我不确定如何让ipython搜索pip安装目录。

我按照网站上的描述再次重新安装了tensorflow:

仍然没有运气:

In [1]: import tensorflow
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

Answer 1

好的，我已经解决了问题。

我不确定到底是什么原因造成的。因为我在我的 RMBP 上安装了所有这些，没有错。但台式机无法接受。

解决方法是:

卸载所有以前安装或安装了一半的tensorflow，以及我的其他包(只有两个主要包)。并使用anaconda安装tensorflow，激活。并使用 anaconda 安装我的其他包。

然后问题就解决了。
