当我使用 subprocess.Popen 运行 cts 时，它总是进入非交互模式然后停止。
非交互模式：运行初始命令然后退出。
下面是我使用的代码。
subprocess.Popen（command_list，stdout=subprocess.PIPE，stderr=subprocess.STDOUT）
Android CTS 5.1_r5
Non-interactive mode: Running initial command then exiting.
Using commandline arguments as starting command: [run, cts, --plan, CTS, -s, JS2U300154120087, --disable-reboot]
