python - 尝试加载 Librosa 的示例文件时找不到文件错误

问题描述

我正在使用 Librosa 编写我的第一个程序，所以我从他们的文档中复制了一些代码，看看我是否可以让它工作。尝试加载示例文件时出现文件未找到错误，我不知道原因。我发现一些人说他们没有后端错误（https://github.com/librosa/librosa/issues/743，https://github.com/beetbox/audioread/issues/54）我想知道这是否与我的问题有关？如果这有所作为，我正在使用 PyCharm

这是我的代码：

import librosa

filename = librosa.util.example_audio_file()
y, sr = librosa.load(filename)
print(y)

这是错误消息：

Traceback (most recent call last):
  File "C:/Users/owner/PycharmProjects/SongVisualizer/SongVisualizer.py", line 11, in <module>
    y, sr = librosa.load(filename)
  File "C:\Users\owner\PycharmProjects\SongVisualizer\venv\lib\site-packages\librosa\core\audio.py", line 119, in load
    with audioread.audio_open(os.path.realpath(path)) as input_file:

    if ffdec.available():

  File "C:\Python37\lib\subprocess.py", line 1178, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

任何帮助将不胜感激
