请问下 uiautomator2 的版本号是多少呢

数据库装老版本可以了，但是后面报这个

  File "D:\Projects\Python\ATX-Test-master\Public\devices_new.py", line 30, in atxserver2_online_devices
    if i.get():
  File "C:\Users\XXXXXXX\AppData\Local\Programs\Python\Python37\lib\multiprocessing\pool.py", line 657, in get
    raise self._value
AttributeError: 'Device' object has no attribute '_filelock'

4.5.1

请问下，取 atx2 的设备，然后这个报错是什么情况
``py
File "D:/Projects/Python/ATX-Test-master/Demo/TestSuite_demo/run_cases.py", line 29, in
devices = check_devives(dm_config.method, dm_config.udid)
File "D:\Projects\Python\ATX-Test-master\Public\devices_new.py", line 133, in check_devives
devices = atxserver2_online_devices(atxserver2().present_android_devices())
File "D:\Projects\Python\ATX-Test-master\Public\atxserver2.py", line 139, in present_android_devices
self.refresh()
File "D:\Projects\Python\ATX-Test-master\Public\atxserver2.py", line 91, in refresh
self.purge()
File "D:\Projects\Python\ATX-Test-master\Public\atxserver2.py", line 106, in purge
self.db.purge_tables()
File "C:\Users\xxxxxxx\AppData\Local\Programs\Python\Python37\lib\site-packages\tinydb\database.py", line 255, in __getattr_
return getattr(self.table(self.default_table_name), name)
AttributeError: 'Table' object has no attribute 'purge_tables'

请问下，屏幕是会灰的是因为 minicap 的问题吗？
