Question

我正在尝试在Macbook中使用tensorflow进行研究。我使用pip3在系统中安装tensorflow（不在虚拟环境中）。

首先，我只想验证tensorflow是否可以通过python3在终端中正确导入。但是，有时在导入时遇到以下问题。

>>>import tensorflow as tf
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/cyan/Library/Python/3.5/lib/python/site-packages/tensorflow/__init__.py", line 24, in <module>
from tensorflow.python import pywrap_tensorflow  # pylint: disable=unused-import
  File "/Users/cyan/Library/Python/3.5/lib/python/site-packages/tensorflow/python/__init__.py", line 47, in <module>

  File "/Library/Python/2.7/site-packages/numpy/add_newdocs.py", line 13, in <module>
from numpy.lib import add_newdoc
  File "/Library/Python/2.7/site-packages/numpy/lib/__init__.py", line 8, in <module>
from .type_check import *
  File "/Library/Python/2.7/site-packages/numpy/lib/type_check.py", line 11, in <module>
import numpy.core.numeric as _nx
  File "/Library/Python/2.7/site-packages/numpy/core/__init__.py", line 14, in <module>
from . import multiarray
ImportError: dlopen(/Library/Python/2.7/site-packages/numpy/core/multiarray.so, 2): Symbol not found: _PyBuffer_Type
  Referenced from: /Library/Python/2.7/site-packages/numpy/core/multiarray.so
  Expected in: flat namespace in /Library/Python/2.7/site-packages/numpy/core/multiarray.so

仅当我在执行python3之前首先运行以下代码时，才能解决此错误

unset PYTHONPATH

如果没有取消设置PYTHONPATH，使用

检查pip3的版本时也会发现错误。

pip3 --version

错误如下所示。

>> pip3 --version

raise ImportError('This package should not be accessible on Python 3. '
ImportError: This package should not be accessible on Python 3. Either you are trying to run from the python-future src folder or your installation of python-future is corrupted.

我认为每次都取消设置PYTHONPATH太不方便了，那么对此问题有什么解决方案吗？我还想在其他文本编辑器（例如Sublime和Pycharm）中导入tensorflow，所以我真的不确定下一步该怎么做。

我尝试了相同的情况。对我来说很好。在第一个错误中，您的python安装似乎被搞砸了。如果在终端中使用python3，则不应引用2.7库。

我也不认为您每次都需要取消设置PYTHONPATH。第一件事是您不需要设置PYTHONPATH。似乎安装出现问题。

您在Mac中使用自制软件来安装软件包。如果没有，我会说使用自制软件，它会起到魅力。由于它适当地增加了依赖性。

无法在python3和ImportError中导入tensorflow：此软件包在Python 3上不可访问
