不能导入python模块，除非是root用户

Question

当我从一个普通用户打开python时，我无法在终端中导入python模块（尽管它适用于root用户）：
我得到的错误是：

import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/numpy/__init__.py", line 180, in <module>
    from . import add_newdocs
  File "/usr/lib/python2.7/dist-packages/numpy/add_newdocs.py", line 13, in <module>
    from numpy.lib import add_newdoc
  File "/usr/lib/python2.7/dist-packages/numpy/lib/__init__.py", line 8, in <module>
    from .type_check import *
  File "/usr/lib/python2.7/dist-packages/numpy/lib/type_check.py", line 11, in <module>
    import numpy.core.numeric as _nx
  File "/usr/lib/python2.7/dist-packages/numpy/core/__init__.py", line 58, in <module>
    from numpy.testing.nosetester import _numpy_tester
  File "/usr/lib/python2.7/dist-packages/numpy/testing/__init__.py", line 12, in <module>
    from . import decorators as dec

    from .utils import SkipTest
  File "/usr/lib/python2.7/dist-packages/numpy/testing/utils.py", line 15, in <module>
    from tempfile import mkdtemp, mkstemp
  File "/usr/lib/python2.7/tempfile.py", line 32, in <module>
    import io as _io
  File "/home/praneeth/computervision/code/caffe-master/distribute/python/caffe/io.py", line 2, in <module>
    import skimage.io
  File "/home/praneeth/scikit-image/skimage/__init__.py", line 158, in <module>
    from .util.dtype import *
  File "/home/praneeth/scikit-image/skimage/util/__init__.py", line 1, in <module>
    from .dtype import (img_as_float, img_as_int, img_as_uint, img_as_ubyte,
  File "/home/praneeth/scikit-image/skimage/util/dtype.py", line 8, in <module>
    dtype_range = {np.bool_: (False, True),
AttributeError: 'module' object has no attribute 'bool_'

所有模块都是一样的，不仅仅是numpy。我试过其他类似问题中提出的解决办法，但都没有成功。例如： Cannot import a python module that is definitely installed (mechanize)

{cd1>的输出是^：

/home/praneeth/computervision/code/caffe-master/distribute/python/caffe:/home/praneeth/computervision/code/caffe-master/python/caffe:/usr/lib/python2.7/dist-packages/

另外，没有root权限的系统路径是：

^{pr2}$

编辑1: 系统路径发现with root用户与不带root用户的用户相同，但需要这些caffe安装路径。下面是根用户的结果：

sudo python

终于解决了！！这个问题是因为在安装caffe时，分别为python和其他版本的numpy安装numpy和scipy（使用不同的版本）。两个与numpy和scipy相关的库之间存在版本冲突，因此python解释程序无法导入它们。在

再次正确地重新安装了caffe，这次没有任何版本冲突，问题得到了解决。在

谢谢你的帮助
