I got an Intel RealSense D435 deep camera, so I write a simple demo as blow to learn its use

import pyrealsense2 as rs
import numpy as np
import cv2


pipeline = rs.pipeline()
config = rs.config()
config.enable_stream(rs.stream.depth, 640, 480, rs.format.z16, 30)
config.enable_stream(rs.stream.color, 640, 480, rs.format.bgr8, 30)


pipeline.start(config)

try:
    while True:
        frames = pipeline.wait_for_frames()
        depth_frame = frames.get_depth_frame()
        color_frame = frames.get_color_frame()
        if not depth_frame or not color_frame:
            continue

        
        depth_image = np.asanyarray(depth_frame.get_data())
        color_image = np.asanyarray(color_frame.get_data())

        
        cv2.imshow('Depth Image', depth_image)
        cv2.imshow('Color Image', color_image)

        if cv2.waitKey(1) & 0xFF == ord('q'):
            break
finally:
    pipeline.stop()
    cv2.destroyAllWindows()

But it only shows few frames and exits with errors blow:
enter image description here

I tried to lengthen the time pipeline wait for frame as its default value is 5000ms,and I also tried to add assert judge–if this error occurs, reset the camera and pipeline, it has some help, but usefulness, because it cost a lot of time to display a frame, and most of the time it shows the error as the picture above shows.
My CPU is intel i7-13650HX, so I didn’t think it related to my laptop’s computation ability.
