我尝试在linux Raspbian上使用python kivy调用可执行文件。 我的代码工作不正常，按下按钮我的应用程序冻结，而不是打开可执行文件。 我试过python解释器：
>> from subprocess import call
>> call("7w.sh")
工作正常，在python kivy可执行文件中没有打开...
为什么可执行文件无法打开？ 我的代码：
Main.py
from kivy.uix.floatlayout import FloatLayout
from kivy.app import App
from kivy.config import Config
Config.set('graphics', 'width', '800')
Config.set('graphics', 'height', '480')

请试试这个：
>>>import subprocess
>>>p = subprocess.Popen(["bash", "7w.sh", ""])
>>>p.communicate()
我在Minibian的Raspberry Pi 3上使用Python3进行了测试
