TypeError: setText(self, str): argument 1 has unexpected type 'tuple'

Question

I created a code in which, when "load" is clicked, the user will upload a .png image and opencv will perform houghcircle and count the circles.

and the count, will be displayed on the textlabel. The circles.shape would result to (1, 99, 3), and I want to display 99, or even the whole (1, 99, 3) on the textlabel.

the problem is, I get this error after uploading the image

Traceback (most recent call last): File "try.py", line 58, in Browse self.label_2.setText(circles.shape) TypeError: setText(self, str): argument 1 has unexpected type 'tuple'

Here is my code:

def Browse(self):
    filter = "Images (*.png)"
    fname, _ = QFileDialog.getOpenFileName(self, "Open Image", "Desktop", filter)
    print(fname)
    self.scene = QGraphicsScene()
    self.scene.addPixmap(QPixmap(fname))
    self.graphicsView_2.setScene(self.scene)

    img = cv2.imread(fname,0)
    cimg = cv2.cvtColor(img,cv2.COLOR_GRAY2BGR)

    circles = cv2.HoughCircles(img,cv2.HOUGH_GRADIENT,1,5,
                        param1=200,param2=8,minRadius=0,maxRadius=7)

    circles = np.uint16(np.around(circles))
    for i in circles[0,:]:
        # draw the outer circle
        cv2.circle(cimg,(i[0],i[1]),i[2],(0,255,0),1)
        # draw the center of the circle
        cv2.circle(cimg,(i[0],i[1]),2,(0,0,255),1)
    numberofcells = print(circles.shape)
    self.label_2.setText(circles.shape) 

any help would be appreciated. Thank you so much!

Answer 1

setText() expects a string but you are passing it a tuple, a possible solution is:

self.label_2.setText(str(circles.shape))
