我在 Jupyter 上使用 Python 3，我试图找出音频文件（有一些噪音）与没有原始文件的准确性。请在下面找到我在网上找到的代码，
import librosa
import matplotlib.pyplot as plt
from dtw import dtw
#Loading audio files
y1, sr1 = librosa.load('data/dev1_female3_liverec_130ms_1m_sim_1.wav')
y2, sr2 = librosa.load('data/dev1_female3_liverec_130ms_1m_sim_1o.wav')
#Showing multiple plots using subplot
plt.subplot(1, 2, 1)
mfcc1 = librosa.feature.mfcc(y1,sr1) #Computing MFCC values
librosa.display.specshow(mfcc1)
plt.subplot(1, 2, 2)
mfcc2 = librosa.feature.mfcc(y2, sr2)
librosa.display.specshow(mfcc2)
dist, cost, path = dtw(mfcc1.T, mfcc2.T)
print("The normalized distance between the two : ",dist) # 0 for similar audios
plt.imshow(cost.T, origin='lower', cmap=plt.get_cmap('gray'), interpolation='nearest')
plt.plot(path[0], path[1], 'w') #creating plot for DTW
plt.show()
我收到一个错误“找不到模块名称 librosa”
