Hello，did you have the same problem? The demo.py can finally be executed, but I cannot see a normal "display window".

I haven't met this.

but I cannot see a normal "display window".

Are you running the script on via ssh or on a desktop? We use cv2.imshow to display the window. It doesn't work when you are using ssh.

@xingyizhou Thanks for you reply. I ran the script on Ubuntu16.04 without using ssh. I updated the Qt style by the following conmands:

• ~/.config/Trolltech.conf

• then add another style in the Trolltech.conf: [Qt] style = QtCurve

  It allows me to run the demo.py normally, but I still cannot see a normal "display window". So I put it for a while.
