使用 scipy 时未找到模块

Question

我最近正确安装了 numpy 和 scipy。以下行运行没有错误。

import scipy

我在使用 scipy.io.wavefile 时遇到困难。我一直在尝试使用 this post 的 "best answer" 中的代码。

但是，当我尝试第一行时，

from scipy.io import wavfile

我收到以下错误和回溯，

Traceback (most recent call last): File "<pyshell#0>", line 1, in <module> from scipy.io import wavfile File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\io\__init__.py", line 97, in <module> from .matlab import loadmat, savemat, whosmat, byteordercodes File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\io\matlab\__init__.py", line 13, in <module> from .mio import loadmat, savemat, whosmat File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\io\matlab\mio.py", line 12, in <module> from .miobase import get_matfile_version, docfiller File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\io\matlab\miobase.py", line 22, in <module> from scipy.misc import doccer File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\misc\__init__.py", line 68, in <module> from scipy.interpolate._pade import pade as _pade File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\interpolate\__init__.py", line 175, in <module> from .interpolate import * File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\interpolate\interpolate.py", line 21, in <module> import scipy.special as spec File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\special\__init__.py", line 640, in <module> from ._ufuncs import * File "_ufuncs.pyx", line 1, in init scipy.special._ufuncs ImportError: DLL load failed: The specified module could not be found.

如果我改为尝试以下行，我也会收到错误和回溯，

import scipy.io.wavfile

收到不同的回复，

Traceback (most recent call last): File "<pyshell#1>", line 1, in <module> import scipy.io.wavfile File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\io\__init__.py", line 97, in <module> from .matlab import loadmat, savemat, whosmat, byteordercodes File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\io\matlab\__init__.py", line 13, in <module> from .mio import loadmat, savemat, whosmat File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\io\matlab\mio.py", line 12, in <module> from .miobase import get_matfile_version, docfiller File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\io\matlab\miobase.py", line 22, in <module> from scipy.misc import doccer File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\misc\__init__.py", line 68, in <module> from scipy.interpolate._pade import pade as _pade File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\interpolate\__init__.py", line 175, in <module> from .interpolate import * File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\interpolate\interpolate.py", line 21, in <module> import scipy.special as spec File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\special\__init__.py", line 642, in <module> from .basic import * File "C:\Users\Me\AppData\Local\Programs\Python\Python37-32\lib\site-packages\scipy\special\basic.py", line 15, in <module> from ._ufuncs import (ellipkm1, mathieu_a, mathieu_b, iv, jv, gamma, ImportError: cannot import name 'ellipkm1' from 'scipy.special._ufuncs' (unknown location)

不明白为什么找不到模块，如果scipy安装正确，可以自己导入。我正在使用 python 3.7.1。来自 post 的代码可以折旧吗？提前为冗长的 post.

道歉

两条错误消息都在抱怨 scipy.special._ufuncs 模块，快速搜索显示了一些其他帖子，like this one, that suggest making sure you have the Visual C++ Redistributable Packages installed: https://www.microsoft.com/en-us/download/details.aspx?id=48145
