NameError: name 'self' is not defined

What will you do with the image?

The code you've posted has no imports for numpy and cv2, it's not the full code?

something like that

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
import cv2
import numpy as np

class Win():
    def __init__(self):
        window = QMainWindow()
        window.show()
 
    def getFrame(self):
        fp = r'/home/UbuntuUser/Desktop/UAV.tif'
        self.img = cv2.imdecode(np.fromfile(fp, dtype=np.uint8), cv2.IMREAD_UNCHANGED)
        print(self.img)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    win = Win()
    win.getFrame()
    sys.exit(app.exec_())
