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。
