pyqt5使用QGraphicsView控件显示图片

Question

pyqt5界面设计，在QGraphicsView控件上显示照片
下面代码有什么问题？怎么在graphicsView_1控件上显示图片

import sys
import os
from PyQt5.QtWidgets import QApplication, QMainWindow, QFileDialog, QMessageBox, QGraphicsView, QGraphicsScene, \
    QGraphicsPixmapItem
from PyQt5.QtGui import QPixmap, QImage
from untitled import Ui_MainWindow
import cv2

class show_photo(QMainWindow):
    def __init__(self):
        super(show_photo, self).__init__()
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)

    def img_open(self):
        file_name = QFileDialog.getOpenFileName(self, "Open File", "./", "jpg (*.jpg)")
        image_path = file_name[0]
        if (file_name[0] == ""):
            QMessageBox.information(self, "提示", self.tr("没有选择图片文件！"))
        print(image_path)
        img = cv2.imread(image_path)  # 读取图像
        img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)  # 转换图像通道
        x = img.shape[1]  # 获取图像大小
        y = img.shape[0]
        self.zoomscale = 1  # 图片放缩尺度
        frame = QImage(img, x, y, QImage.Format_RGB888)
        pix = QPixmap.fromImage(frame)
        self.item = QGraphicsPixmapItem(pix)  # 创建像素图元
        self.scene = QGraphicsScene()  # 创建场景
        self.scene.addItem(self.item)
        self.view.setScene(self.scene)
        self.graphicsView_1.setScene(scene)

if __name__ == "__main__":
    app = QApplication(sys.argv)
    mainWindow = show_photo()
    mainWindow.show()
    sys.exit(app.exec_())

Answer 1

self.view.setScene(self.scene)改为self.ui.graphicsView_1.setScene(self.scene)看看
