如何在Kivy Launcher中运行OpenCV? [英] How to run OpenCV in Kivy Launcher?

问题描述

我正在构建需要OpenCV模块的Kivy应用程序，但是运行Kivy Launcher时，它总是崩溃.

I am building a Kivy app that requires the OpenCV module, but the Kivy Launcher keeps crashing when I run it.

我已经从PyPi下载了OpenCV( https://pypi.python.org/pypi/opencv-python#downloads )，并将其放入我的kivy项目目录中.我的项目目录当前包含main.py文件，android.txt文件和opencv下载.在main.py文件中，我在代码顶部编写了"import cv2".但是，我的应用程序在Kivy启动器中不断崩溃.

I have downloaded OpenCV from PyPi (https://pypi.python.org/pypi/opencv-python#downloads) and placed it into my kivy project directory. My project directory currently contains the main.py file, the android.txt file, and the opencv download. In the main.py file I write "import cv2" at the top of the code. However, my app keeps crashing in the Kivy launcher.

安装在Kivy Launcher中使用的python扩展的正确方法是什么?

推荐答案

我已经从PyPi下载了OpenCV ( https://pypi.python.org/pypi/opencv-python#downloads)并将其放置 进入我的基维项目目录

这不是工作方式. OpenCV应该专门针对Android进行编译.我猜您使用 buildozer 来构建apk吗?在这种情况下，您应该修改buildozer.spec文件中的requirements行以添加opencv，例如:

This is not how things work. OpenCV should be compiled specifically for Android. I guess you use buildozer to build apk? In this case you should modify requirements line inside buildozer.spec file to add opencv, for example:

requirements =  kivy, opencv

为Android 提供 python-for-android项目.
