Question

我尝试使用Chaquopy在我的android应用中运行python代码，我也在使用moviepy库（我正在将mp4文件转换为gif文件）。当我尝试进行转换时，出现以下错误消息：

我已经找到了解决此问题的方法（它涉及changing the python code，通常由android studio生成，因此对python文件的任何更改都将在构建期间被覆盖。

下面显示了python代码

from moviepy.editor import VideoFileClip

def convert(path):
    clip = VideoFileClip(path)
    return clip.write_gif("output.gif", fps=24)

用于启动pyhton代码的Java代码：

Python.start(new AndroidPlatform(getActivity()));
        Python py = Python.getInstance();
        PyObject gifConvert = py.getModule("gif_convert");
        PyObject gif = gifConvert.callAttr("convert", file.getAbsolutePath());
        Log.i("gif type", gif.toString());

任何帮助将不胜感激。

较早版本的Chaquopy遇到pkgutil.iter_modules问题。这是fixed in Chaquopy 6.2.1。

在具有chaquopy的android应用中运行python会产生致命错误
