任何人都可以帮助我吗？我是一个关于蟒蛇的新人。

我想运行一个Python项目，在Raspberry pi零W中证明是正确的，它上面的系统是像Debian一样的linux，我已经安装了Python 2和python 3。

当我杀死上述错误时，出现了另一个错误，如下所示：

以前有人遇到类似问题吗？

Answer 1

解决OSError: [Errno 2] No such file or directory

的方法

安装FFmpeg或Libav

原因FFmpeg几乎被Linux退出，我安装了Libva

sudo apt-get install libav-tools

解决MemoryError

的方法

将小型mp3文件更改为指纹并重新识别

因为我的CPU的RAM太小而无法处理大文件

Linux | Python | `OSError：[Errno 2]没有这样的文件或目录`＆amp; `MemoryError`
