“No Backend Error” while reading files in Python

问题

I am trying to perform STFT on a bunch of sound files and I get this error. The path of the files which I am trying to perform STFT is correct but still, I get this error.

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)

Output:

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

     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

Can anyone tell me why I have this error?
