PyForms GUI: ImportError: /../PyQt5/QtWidgets.abi3.so: undefined symbol: _ZdlPvm, version Qt_5

Question

I am trying to understand what pyforms can offer me. I am running one basic example: link. I am running into issues. No success so far. I am running it on the Kaggle browser notebook.

code:

!pip install pyforms
import pyforms
from   pyforms          import BaseWidget
from   pyforms.controls import ControlText
from   pyforms.controls import ControlButton

class SimpleExample1(BaseWidget):

    def __init__(self):
        super(SimpleExample1,self).__init__('Simple example 1')

        #Definition of the forms fields
        self._firstname     = ControlText('First name', 'Default value')
        self._middlename    = ControlText('Middle name')
        self._lastname      = ControlText('Lastname name')
        self._fullname      = ControlText('Full name')
        self._button        = ControlButton('Press this button')


#Execute the application
if __name__ == "__main__":   pyforms.start_app( SimpleExample1 )

present output:
