SOS，一个有趣的 Python 库

This topic created in 1274 days ago, the information mentioned may be changed or developed.

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

import

Data

nbeats

audio

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。

@craiiz 这个试过了没用
