我正在尝试使用https://pypi.org/project/pypjlink2/查询一些正在工作的NEC投影机，有些模型可以工作，但是有些给出AssertionError。
我确保在投影机上没有配置密码，还尝试定义密码并将其放在放映机中。authenticate（'mypassword'）
ip = raw_input('ip address: ')
projector = Projector.from_address(ip)
projector.authenticate('')
projector.set_power('on')
errors = projector.get_errors()
print errors
