    import os
    import time

    import matplotlib
    import matplotlib.pyplot as plt

    import numpy as np
    import visbeat3 as vb

    source_video = vb.PullVideo(name='video', source_location='./data/01.mp4')

    # You can also directly specify an audio
    source_audio = vb.Audio('./data/111.mp3')
    #source_audio = vb.PullVideo(name='audio', source_location='./data/02.mp4')

    synch_video_beat = 0
    synch_audio_beat = 3
    nbeats = 32

    output_path = './result.mp4'

    # If source_audio is from an audio file, use target=source_audio
    warped = vb.Dancify(source_video=source_video,
    target=source_audio.getAudio(),
    synch_video_beat=synch_video_beat,
    synch_audio_beat=synch_audio_beat,
    force_recompute=True,
    warp_type='quad',
    nbeats=nbeats,
    output_path=output_path)


    最后报错:
    FileExistsError: [WinError 183] : './VisBeatAssets/VideoSources\\video\\VideoSource.json' -> './VisBeatAssets/VideoSources\\video\\Data\\Backups\\\\VideoSource.json'

    python 版本:3.8.15
    来个大神指点一下吧

    建议贴上完整的 stack trace 和报错信息。光看你这个报错,看起来像是重复执行某些代码,但没有权限覆盖旧的文件

    调试:
    os.rename(self.getJSONPath(), self.getDir('backup') + os.sep + self.AOBJECT_TYPE() + ".json");

    https://docs.python.org/3/library/os.html

    On Windows, if dst exists a FileExistsError is always raised.
    On Unix, ... If both are files, dst will be replaced silently if the user has permission.

    @y4nssss 估计你把 VideoSource.json 这个删掉就可以了。因为什么程序在你脚本运行的时候占用了这个文件,导致你的脚本无法覆盖它。因为 windows 文件打开的时候是更改它的,但 linux 可以。
