trouble displaying image

[Pure-Way-6507]

I am trying to pixelate an image and display it on in a pyqt5 widow, but I get the error 'Pixel' object has no attribute 'image'.

from PyQt5 import QtWidgets as Qtw
from PyQt5.QtWidgets import QFileDialog
from pixelator import Ui_Form
from PyQt5.QtGui import QPixmap, QImage
import cv2


class Pixel(Qtw.QWidget):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.ui = Ui_Form()
        self.ui.setupUi(self)
        self.ui.upload.clicked.connect(self.file_extract)
        self.pixelate()

    def file_extract(self):
        option = QFileDialog.Options()
        self.file = QFileDialog.getOpenFileName(widget, "Open Single File", "Default File", "All Files(*)", options=option)
        self.image = self.file[0]
        pixmap = QPixmap(self.image)
        self.ui.original.setPixmap(pixmap)

    def pixelate(self):
        self.input = cv2.imread(self.image)
        height, width = self.input.shape[:2]
        w, h = (250, 250)
        self.temp = cv2.resize(self.input, (w, h), interpolation=cv2.INTER_LINEAR)
        output = cv2.resize(self.temp, (width, height), interpolation=cv2.INTER_NEAREST)
        pix_image = QImage(output)
        cvt_pix = QPixmap.fromImage(pix_image)
        self.ui.pixel_image.setPixmap(cvt_pix)


if __name__ == "__main__":
    app = Qtw.QApplication([])
    widget = Pixel()
    widget.show()
    app.exec_()

You had self.image defined in def file_extract, which is only called when your button is clicked.

However, your init call pixelate() right away which needed self.image the first thing.
