我正在使用以下代码来获取WAV文件的BPMS,但是如何输入音频文件?

我试着跑

    bpm_detection.py --filename

但出现IO错误

主要功能如下:

    if __name__ == '__main__':
        parser = argparse.ArgumentParser(description='Process .wav file to 
    determine the Beats Per Minute.')
        parser.add_argument('--filename', required=True,
               help='.wav file for processing')
        parser.add_argument('--window', type=float, default=3,
               help='size of the the window (seconds) that will be scanned to determine the bpm.  Typically less than 10 seconds. [3]')

        args = parser.parse_args()
        samps,fs = read_wav(args.filename)

采用

python file.py --filename file.wav

要么

python file.py --filename C:\path\path\test.wav

要么

python file.py --filename C:\\path\\path\\test.wav

要么

python file.py --filename ./test.wav
