python x86 ImportError：DLL加载失败

Question

我有win7 x64的系统和之前使用Anaconda2-2.4.0-Windows- x86

的代码

from sklearn.linear_model import LinearRegression

但现在我明白了：

File "C:\Anaconda2\lib\site-packages\sklearn\linear_model\__init__.py", line 1
2, in <module>
    from .base import LinearRegression
  File "C:\Anaconda2\lib\site-packages\sklearn\linear_model\base.py", line 28, i
n <module>
    from ..utils import as_float_array, check_array, check_X_y
  File "C:\Anaconda2\lib\site-packages\sklearn\utils\__init__.py", line 16, in <
module>
    from .class_weight import compute_class_weight, compute_sample_weight
  File "C:\Anaconda2\lib\site-packages\sklearn\utils\class_weight.py", line 7, i
n <module>
    from ..utils.fixes import in1d
  File "C:\Anaconda2\lib\site-packages\sklearn\utils\fixes.py", line 318, in <mo

    from scipy.sparse.linalg import lsqr as sparse_lsqr

    from .matfuncs import *

, in <module>
    import scipy.misc
  File "C:\Anaconda2\lib\site-packages\scipy\misc\__init__.py", line 49, in <mod
ule>
    from scipy.special import comb, factorial, factorial2, factorialk
  File "C:\Anaconda2\lib\site-packages\scipy\special\__init__.py", line 601, in
<module>
    from ._ufuncs import *
ImportError: DLL load failed: The specified procedure could not be found.

昨天，我已经安装了software，它自带了一些python，看起来在安装过程中做了别的事情。 在Dependency walker中，我看到以下图片：

我已经安装了Anaconda2-2.4.0-Windows-x86_ 64 ，在这个python版本中一切正常。

您能否帮我理解系统中已更改的内容以及我如何修复它？（我已完全删除已安装的软件但没有帮助）
