Running the converted py to exe file shows a console and not the designed GUI

Question

I want to create a GUI EXE file I am creating a a GUI using python 3.6 and PyQt5, After running .py file I get the design that I worked on. However when i convert the .py file to an exe using Cx_Freeze or pyinstaller, then I run the EXE file, GUI doesn't show and a console shows instead.

import sys 
from PyQt5.QtCore import pyqtSlot
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.uic import loadUi

completed = 0
accumulate = 0
class Main(QMainWindow):
    def __init__(self):
        super(Main, self).__init__()
        loadUi('progress.ui',self)
        self.setWindowTitle('Greeting')
        self.progressBar.setValue(0)
        self.increase.clicked.connect(self.increase_by10)
        self.reset.clicked.connect(self.resetprogress)

    @pyqtSlot()
    def increase_by10(self):
        global accumulate
        accumulate += 10
        if accumulate <= 100:
                self.progressBar.setValue(accumulate)

    @pyqtSlot()
    def resetprogress(self):
        global accumulate
        accumulate = 0
        self.progressBar.setValue(accumulate)
        
      
              
app = QApplication(sys.argv)
widget = Main()
widget.show()
sys.exit(app.exec_())

• running .py file
• running .exe converted from .py

1. ...\Python\Scripts\pyuic5.exe progress.ui -o progress.py -x

2. + (progress.py) # - (progress.ui)

3. pyinstaller --onefile --noconsole main.py
4. main.exe

main.py
