Use Ubuntu 22.04 PX4 v1.14 MAVSDK 2.0.1 Hey, I want to control my grippe…r with this code ``` from mavsdk import System from mavsdk.gripper import Gripper import asyncio async def run(): drone = System() await drone.connect(system_address="udp://:14540") print("正在连接无人机...") async for state in drone.core.connection_state(): if state.is_connected: print("-- 无人机已连接!") break print("正在等待定位...") async for health in drone.telemetry.health(): if health.is_global_position_ok and health.is_home_position_ok: print("-- 定位已准备好!") break gripper = Gripper(drone) await gripper.release(1) asyncio.run(run()) ``` But,this error is generated > Traceback (most recent call last): > File "/home/yyy/桌面/模拟测试用/test.py", line 23, in <module> > asyncio.run(run()) > File "/usr/lib/python3.10/asyncio/runners.py", line 44, in run > return loop.run_until_complete(main) > File "/usr/lib/python3.10/asyncio/base_events.py", line 649, in run_until_complete > return future.result() > File "/home/yyy/桌面/模拟测试用/test.py", line 20, in run > gripper = Gripper(drone) > File "/home/yyy/.local/lib/python3.10/site-packages/mavsdk/_base.py", line 10, in __init__ > self._init_plugin(async_plugin_manager) > File "/home/yyy/.local/lib/python3.10/site-packages/mavsdk/_base.py", line 17, in _init_plugin > self._setup_stub(async_plugin_manager.channel) > AttributeError: 'System' object has no attribute 'channel'
