关于这个问题我已经找了几天了,但没有找到解决办法。我有一个很大的脚本(我正在尝试连接大量的视频,~100-500),这就是为什么我得到错误“太多的文件打开”。在阅读Zulko对其他问题的回应时,我发现有必要像这样手动删除每个VideoFileClip实例:
del clip.reader
del clip
我面临的问题是,我有一个简单的hello\u world尝试这样做,但是得到错误VideoFileClip instance has no attribute 'reader'
代码如下:
我正在使用El Capitan(OSX),已经根据需要更新了MoviePy、Numpy、ImageMagick和我看到的所有软件包,但是我仍然收到这个错误。问题是我的电脑有时会死机,因为它占用了太多内存。我目前正在连接25个视频块,并尝试删除所有25个“打开的文件”,连接下一个25个,等等。之后,我将连接较长的视频。在
请注意,没有del行新视频阅读器我仍然收到错误打开了太多的文件
当我尝试运行真实的脚本时,如果不添加新视频阅读器在

按照泰恩的要求,我将发布“真实代码”。我在这里要做的是,正如我上面所解释的,把25个视频分成块,然后把所有这些预先编译好的视频编译成一个大的视频。我现在得到错误Too Many Files Open

祖尔科本人:
这是在0.2.2版发布之前。所以看起来你不需要做
del clip.reader
。在更确切地说,你不能这样做!
VideoFileClip
为您定义一个析构函数:但既然你已经删除了它,你就会得到
AttributeError
:在
<bound method VideoFileClip.__del__ of <...VideoFileClip instance at 0x13..>>
我已经解决了我的问题,这个问题在https://github.com/Zulko/moviepy中有详细描述。在
安装ImageMagick后,MoviePy将自动检测到它,但在Windows上除外!在手动安装MoviePy之前,Windows用户需要编辑
moviepy/config_defaults.py
以提供ImageMagick二进制文件的路径,该路径称为convert。应该是这样的: ^{相关问题 更多 >
