Error when running DEMO_GUI.py

[Jerry-muyangren]

Hello, I have initialized environments based on your readme file:

Ubuntu 16.04
Keras 1.1.0
matplotlib 3.3.4
numpy 1.19.5
opencv-python 4.5.1.48
pygpu 0.7.6
PyQt5 5.15.4
python 3.6.13
theano 1.0.2

But when I try to run Demo_GUI file it occurred an error about the numpy. Can you advise me what happened and how to fix it?
Thank you.
