Librosa帮助读取音频文件，但是在我的情况下，当我输入文件名时，找不到运行时错误路径

Question

我正在一个项目上，但是我的问题是我的librosa库向我显示找不到该文件，但是它存在。

# Load using Librosa
y, sr = librosa.load(normal_file, duration=5)   #default sampling rate is 22 HZ     
dur=librosa.get_duration(y)
print ("duration:", dur)
print(y.shape, sr)

错误：

FileNotFoundError
