Question

我只想从scipy.io导入wavfile。

import scipy                 # this works
import scipy.io              # this does NOT work
from scipy.io import wavfile # does NOT work

是的，我重新安装了4次python。是的，我也尝试过多次通过Anaconda安装。是的，我尝试过Anaconda 2.7和3.5。不，它不起作用。请帮忙。

Answer 1

您的scipy安装已损坏。它应该工作。

In [1]: from scipy.io import wavfile

In [2]: wavfile?
Type:        module
String form: <module 'scipy.io.wavfile' from '/home/br/repos/scipy/build/testenv/lib/python2.7/site-packages/scipy/io/wavfile.pyc'>
File:        /home/br/repos/scipy/build/testenv/lib/python2.7/site-packages/scipy/io/wavfile.py
Docstring:
Module to read / write wav files using numpy arrays

Functions
---------
`read`: Return the sample rate (in samples/sec) and data from a WAV file.

`write`: Write a numpy array as a WAV file.

In [3]: wavfile.<TAB>
wavfile.KNOWN_WAVE_FORMATS      wavfile.numpy
wavfile.WAVE_FORMAT_EXTENSIBLE  wavfile.print_function
wavfile.WAVE_FORMAT_IEEE_FLOAT  wavfile.read
wavfile.WAVE_FORMAT_PCM         wavfile.struct
wavfile.WavFileWarning          wavfile.sys
wavfile.absolute_import         wavfile.warnings
wavfile.division                wavfile.write

Answer 2

这是numpy mkl文件的问题。转到https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy并下载相关版本的numpy + mkl，然后使用该版本重新安装numpy。

Python：即使安装了scipy，也无法导入scipy.io
