PyQt5 on Windows in Python 2.7: Error importing QtWidgets

Question

I downloaded PyQt5 executable file on Windows 7 for python 2.7 both 64bit versions.

Is installed on C:\\Python27\\Lib\\site-packages\\PyQt5

I'm trying to use the above code:

from PyQt5.QtWidgets import QApplication, QDialog 

I get the error:

ImportError: DLL load failed: The specified module could not be found.

I found the QtWidgets on this folder: C:\\Python27\\Lib\\site-packages\\PyQt5\\sip\\PyQt5\\QtWidgets

Do you have any idea?

您确定安装的PyQt5版本与Python版本（32位或64位）兼容吗？
