python-3.6 - 在 Python 中读取文件时出现 "No Backend Error"

Question

我正在尝试对一堆声音文件执行 STFT，但出现此错误。我尝试执行 STFT 的文件路径是正确的，但我仍然收到此错误。

import librosa
import io
import numpy as np
import tensorflow as tf
import os
import glob


path_te = "C:\Users\aanum\OneDrive\Documents\Deep Learning\timit-homework\te"
files = os.listdir(path_te)
for file in sorted(files):
    if file.startswith("tex"):

        file_path = path_te2 + "/" + file 

        #file_path = 'r' + "'" + str(file_path) + "'"
        print(file_path)
        st, sr=librosa.load(file_path, sr=None)

输出:

C:/Users/aanum/OneDrive/Documents/Deep Learning/timit-homework/te/tex0000.wav

     10         X=librosa.stft(st, n_fft=1024, hop_length=512)
     11         X_abs = abs(X)

    118     y = []
--> 119     with audioread.audio_open(os.path.realpath(path)) as input_file:
    120         sr_native = input_file.samplerate
    121         n_channels = input_file.channels

    114 
    115     # All backends failed!
--> 116     raise NoBackendError()

NoBackendError

谁能告诉我为什么会出现这个错误？

确保您的.wav 文件没有损坏。您可以使用音频文件阅读器(可以读取 wav 文件)打开文件吗？否则，您的文件已损坏。如果您从开源数据集下载音频文件，则在您手动解压缩文件夹时它们可能已损坏。我建议您再次下载数据集并使用命令行工具解压缩。
