Getting "OSError: [WinError 6] The handle is invalid" in VideoFileClip function
Getting "OSError: [WinError 6] The handle is invalid" in VideoFileClip function
我正在通过导入 moviepy 库使用 python 创建程序，但出现以下错误：

请告诉我解决方法。
不知何故 python.exe 失败了，因为像 VideoFileClip 这样的内部函数在 jupyter-notebook 中给出了错误。
然后我关闭所有内容并重新启动，瞧，错误消失了，现在工作正常。
我在看完视频后通过运行以下命令解决了这个问题。
video_clip.reader.close()
video_clip.audio.reader.close_proc()
见https://github.com/Zulko/moviepy/issues/73 and https://github.com/Zulko/moviepy/issues/164。
对我有用的是关闭资源管理器，正如 gene tsai 所建议的那样。立即工作。当我收到错误时，我正在使用 os.listdir(dirpath)。
在 windows 10，我无法调用 VideoFileClip() 超过 5 次。 clip.close()解决了我的问题，不需要的剪辑需要关闭：
clip = VideoFileClip("asd.mp4")
...
clip.close()
