PyQt5在导入时卡住，但没有错误消息

Question

我用conda安装了PyQt5：conda install-c inso PyQt5=5.6。我有python3.5。当我运行一个使用PyQt5的简单程序时，该程序在PyQt5导入时卡住，并且没有错误消息。它被卡住了大约5秒钟，然后程序就终止了。请看下面我在google上找到的例子。程序卡在from PyQt5.QtWidgets import QApplication, QWidget行上。我可以在C:\Users\user\Anaconda3\Lib\site packages\PyQt5中看到packcage。是什么导致了这种行为
