I suggested you try to run your .py file, not pyuic5 ... -o your.py.

I run .py file but I wanted to show codes, so I have added them to post.

OK, it's time to crack open the (excellent) PyCharm debugger and see where stepping through your code takes you. Any time you spend learning it now will reward you in spades in later life :)

Thanks for all your answers. But first time it GUI shows up, I see that blank. So, I am unable to understand which Widget causes problem. :( how can I debug it

Just for now, comment out all the stuff after loadUi(...). Let's just see whether something you are doing prevents the widget from showing properly. To start with all you're supposed to be trying is seeing how the code you originally showed is working.

Also what is that loadUi() about? I thought you were testing the file you showed was generated, it's a standalone python program?

Are you somehow using both pyuic5 and ui.loadUi()? https://stackoverflow.com/questions/52471705/why-in-pyqt5-should-i-use-pyuic5-and-not-uic-loaduimy-ui

If you are currently generating, say, view.py (as shown earlier) from view.ui, as I said you should at least try running python view.py.

I commented out all the stuff after loadUi and I see still blank GUI.

No, I am using, only ui.loadUi(). I just wanted to show code behind my GUI and I used pyuic5 for that purpose. (just for posting here) . I have a main.py and view.py i call my GUI using ui.loadUi() in view.py

If you are currently generating, say, view.py (as shown earlier) from view.ui, as I said you should at least try running python view.py.

So, I am not geberating view.py

Hi,

I just copy pasted your code and ran it directly in a virtualenv with the latest PyQt5 installed through and worked properly (on macOS).

@SGaist
But the OP is saying that is not his code, he isn't using pyuic...!
He is using loadUi() on his ,ui file instead.... :)

[SGaist]

@JonB I meant the code from his original post.

[JonB]

@SGaist
I know! But he only posted it as an example to illustrate his .ui file :)

I suggested he verify the pyuic output he posted worked as standalone.

So his question is why it doesn't work from uic.loadUi(). Assuming that's what loadUi() calls.

Do you mean this by saying standalone?

from PyQt5.QtWidgets import *
from PyQt5.uic import loadUi

class loadUi_example(QMainWindow):

    def __init__(self):
        super().__init__()
        loadUi("view.ui", self)

app = QApplication([])
window = loadUi_example()
window.show()
app.exec_()

Thank you, yes I can work it, too. But when i try to import it using uic.loadUi(). I see blank screen.
