PIL:ImportError:_imaging扩展是为另一个版本的枕头或PIL构建的

Question

我收到错误:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-4-0f6709e38f49> in <module>()
----> 1 from PIL import Image

C:\Anaconda\lib\site-packages\PIL\Image.py in <module>()
     61     from PIL import _imaging as core
     62     if PILLOW_VERSION != getattr(core, 'PILLOW_VERSION', None):
---> 63         raise ImportError("The _imaging extension was built for another "
     64                           " version of Pillow or PIL")
     65 

ImportError: The _imaging extension was built for another  version of Pillow or PIL

每当我尝试使用PIL库时.我正在尝试加载和处理一堆.gif文件,而我现在正在尝试的是以下内容:

from PIL import Image

尝试不同的方法,通过scipy:

import scipy.ndimage as spnd
os.chdir('C:\\WeatherSink\\data\\')
spnd.imread('2014-11-03-0645.gif')

失败:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-3-23c383b79646> in <module>()
      1 os.chdir('C:\\WeatherSink\\data\\')
----> 2 spnd.imread('2014-11-03-0645.gif')

C:\Anaconda\lib\site-packages\scipy\ndimage\io.pyc in imread(fname, flatten, mode)
     36         from PIL import Image
     37     except ImportError:
---> 38         raise ImportError("Could not import the Python Imaging Library (PIL)"
     39                           " required to load image files.  Please refer to"
     40                           " http://pypi.python.org/pypi/PIL/ for installation"

ImportError: Could not import the Python Imaging Library (PIL) required to load image files.  Please refer to http://pypi.python.org/pypi/PIL/ for installation instructions.

第一种方法指导我安装PIL版本.我尝试模拟getattr(...),并返回None.所以我并不感到意外,因为它不如功能.但有谁知道如何'修复'错误？

我在win7上运行,通过conda管理python2.7.我也尝试删除并重新安装软件包,输出没有任何变化.

非常感谢帮助.

Answer 1

这只是一个安装问题.

如果未安装,请先在系统上安装pip.它也适用于Windows.

升级你的numpy,pip/pillow,scipy:

pip install -U numpy
pip install -U pil/pillow
pip install -U scipy

Windows的最佳选择是使用anaconda.

我认为pip已经安装在conda中.这将解决您的系统版本问题.

In [1]: from PIL import Image

In [2]: import scipy.ndimage as spnd

In [3]: x = spnd.imread('ppuf100X91.gif')

In [4]: print x
[[255 255 255 ..., 255 255 255]
 [255 255 255 ..., 255 255 255]
 [255 255 255 ..., 255 255 255]
 ..., 
 [255 255 255 ..., 255 255 255]
 [255 255 255 ..., 255 255 255]
 [255 255 255 ..., 255 255 255]]

Answer 2

这是python 3.6编辑文件中的问题:C:\Anaconda\lib\site-packages\PIL\Image.py 并更改代码:

if PILLOW_VERSION != getattr(core, 'PILLOW_VERSION', None):
     raise ImportError("The _imaging extension was built for another "
                        " version of Pillow or PIL")

改为:

if core.PILLOW_VERSION != getattr(core, 'PILLOW_VERSION', None):
     raise ImportError("The _imaging extension was built for another "
                        " version of Pillow or PIL")

这将解决问题.问候
