Installing Extensive Testing client on Ubuntu

Has any one successfully installed Extensive Testing Client on Ubuntu. I download the package from the link and I am trying to install it on Ubuntu 17.04.

I am getting the following error.

Traceback (most recent call last):
  File "/usr/lib64/python2.7/site-packages/cx_Freeze/initscripts/__startup__.py", line 14, in run
  File "/usr/lib64/python2.7/site-packages/cx_Freeze/initscripts/Console.py", line 26, in run
  File "../../Main.py", line 94, in <module>
  File "/root/Desktop/app-client/Libs/QtHelper.py", line 38, in <module>
ImportError: No module named PyQt5.QtGui

I already have PythonQT 5 installed. Installed Python version on my machine is Python 2.7.13
