我正在尝试使用pyAudioAnalysis库从 mp3 文件中提取功能。我遇到的问题是我无法让我的 Jupyter Notebook 找到 eyed3，这对于图书馆来说是必不可少的。这是我的代码：

from pyAudioAnalysis import audioBasicIO
from pyAudioAnalysis import audioFeatureExtraction
import matplotlib.pyplot as plt
[Fs, x] = audioBasicIO.readAudioFile("/Users/Kyle/Downloads/sample.rickyxsan - Insane.mp3");
F = audioFeatureExtraction.stFeatureExtraction(x, Fs, 0.050*Fs, 0.025*Fs);
plt.subplot(2,1,1); plt.plot(F[0,:]); plt.xlabel('Frame no'); plt.ylabel('ZCR'); 
plt.subplot(2,1,2); plt.plot(F[1,:]); plt.xlabel('Frame no'); plt.ylabel('Energy'); plt.show()

当我运行时，我收到此错误：

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

      3 import pydub
      4 from pydub import AudioSegment
      5 

ImportError: No module named eyed3

当我尝试“sudo pip install eyed3”时，我得到以下输出：

Requirement already satisfied: eyed3 in /anaconda/lib/python3.5/site-packages
Requirement already satisfied: six in /anaconda/lib/python3.5/site-packages (from eyed3)
Requirement already satisfied: python-magic in /anaconda/lib/python3.5/site-packages (from eyed3)
Requirement already satisfied: pathlib in /anaconda/lib/python3.5/site-packages (from eyed3)

当我尝试“brew install eyed3”时，我得到了这个：

Warning: git-2.11.0 already installed, it's just not linked.
Error: Git must be installed and in your PATH!
Warning: eye-d3-0.7.8 already installed

看起来好像 eyed3 已经安装了，但我不知道如何让我的笔记本找到它。

cel 是对的，看起来安装库的解释器与 jupyter 使用的解释器不同。这是有道理的，因为您正在执行 sudo pip install 而不仅仅是 pip install。我猜该库是由管理员可以访问但不能访问您的本地帐户的 pip 链接版本安装的。

尝试使用以下方法之一：

python -m pip install eyed3

或者

pip install eyed3 --user

也可能是您的 jupyter notebook 使用的环境是使用 conda 设置的。在这种情况下使用：

conda install eyed3
