Python Bokeh: How to update a Toggle button - defined in the main - in a subroutine

With these it helps I think the while loop interferes the Tornado IO_loop. I advice you to use add_periodic_callback instead (Bokeh v1.1.0)
from bokeh.models import Column
from bokeh.plotting import curdoc
from bokeh.models.widgets import Button, Toggle, CheckboxGroup
import time

# def start_loop():
#     while (not button3.active) and (len(cb.active)):
#         time.sleep(1)
#         print(button3.active)
#         print(cb.active)

def check_status():

# button1 = Button(label = "start")
# button1.on_click(start_loop)

button2 = Button(label = "check status")

button3 = Toggle(label = "stop")
cb = CheckboxGroup(labels = ['stop'], active = [0])

curdoc().add_root(Column(button2, button3, cb))
curdoc().add_periodic_callback(check_status, 1000)

Load widget with signal-slot defintions from UI file in main window

I wish this help you Explanation:
When you have created the .ui you have only pointed out that there is a connection between the clicked signal and the init method of the widget, but when you load it using loadUi() and do not pass it as a second parameter a QWidget will use the base class of the design, in your case QWidget, which clearly has no "init" method throwing you that error.

from PyQt5 import QtCore, QtWidgets, uic as pyuic

class Widget(QtWidgets.QWidget):
    def __init__(self, parent=None):
        current_dir = os.path.dirname(os.path.realpath(__file__))
        uifile = os.path.join(current_dir, "serialTandemGUI.ui")
        pyuic.loadUi(uifile, self)

    def init(self):

class MainWindow(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        self.form_widget = Widget()
        _widget = QtWidgets.QWidget()
        _layout = QtWidgets.QVBoxLayout(_widget)

if __name__ == "__main__":
    app = QtWidgets.QApplication.instance() or QtWidgets.QApplication(sys.argv)

    w = MainWindow()
