I have an numpy array with shape (500, 500, 3). And I want it to convert into image and show it using PyQt5.

I'm assuming that the array is of type uint8 and represents the red, green, and blue
You could use Pillow for this, e.g.
from PyQt5 import QtWidgets, QtGui
from PIL import Image, ImageQt
import numpy as np
# generate data
table = np.zeros((256,256,3), dtype=np.uint8)
for i in range(256):
table[:,i,0] = i
table[i,:,1] = i
table[:,:,2] = (2*255 - table[:,:,0] - table[:,:,1]) // 2
# convert data to QImage using PIL
img = Image.fromarray(table, mode='RGB')
qt_img = ImageQt.ImageQt(img)
app = QtWidgets.QApplication([])
w = QtWidgets.QLabel()
w.setPixmap(QtGui.QPixmap.fromImage(qt_img))
w.show()
app.exec()
