我正在尝试使用 Chaquopy 在我的 android 应用程序中运行 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，我收到以下错误消息：

我找到了解决这个问题的方法（它涉及更改通常由 android studio 生成的 python 代码，因此对 python 文件所做的任何更改都将在构建时被覆盖。

python代码如下所示

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。

旧版本的 Chaquopy 在pkgutil.iter_modules. 这已在 Chaquopy 6.2.1 中修复。
