Module not found when using scipy

I have recently properly installed numpy and scipy. The following line runs without error.

import scipy

I am experiencing difficulty using scipy.io.wavefile. I have been trying to use the code from the "best answer" of this post.

However, when I try the first line,

from scipy.io import wavfile

I receive the following error and traceback,

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.

I also receive an error and traceback if I try the following line instead,

import scipy.io.wavfile

receiving a different response,

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)

I do not understand why the module can not be found, if scipy is properly installed and can be imported by itself. I am using python 3.7.1. Could the code from the post be depreciated? Apologies in advance for the long post.

Both error messages are complaining about the scipy.special._ufuncs module and a quick search revealed a few other posts, 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
