So if someone is interest X) , here the solution for solving the problem
image = (dupl * 255).round().astype(np.uint8)
im = bridge.cv2_to_imgmsg(image, encoding="mono8")
The problem is the encoding 64FC4 is not good for visualization , so i decide to take only 1 channel for my depth map , after you need to convert your matrix [0,1] to [0,255] (here uint8) , because Rviz don't like float32 data for image , you need to convert to rgb or mono .
OpenCV prefer data between 0 and 1 ( imshow )
