Pypjlink是一款通用的投影機控制API，可以通過網絡控制投影機。這裏是一個包含所有關於它的信息的鏈接：https://pypi.python.org/pypi/pypjlink。還有一個指向包含所有文件的存儲庫的鏈接。我一直試圖擺脫所有的斷言錯誤，但我沒有取得太多的成功。只要我修理一個，另一個仍然在我的路上。我只是在查詢投影機的電源狀態。這裏是我的文件中的代碼：我在使用PYPJLINK時遇到斷言錯誤，我該如何解決它們？
from pypjlink import Projector
projector = Projector.from_address('10.21.24.7')
power = projector.get('POWR')
print power
這是所有從測試我的產出在過去的兩個小時：

一些額外的信息：我在與網絡連接的投影機一個靜態IP。這是一臺BenQ投影機，我有一個pjlink命令列表。如果我嘗試發送一個命令，它會起作用，但我仍然會遇到該錯誤。該計劃很難接受答覆。
