  Hi Kenji Yasuda,
  I think there is an example for extracting the IMU data you can refer to for implementation details.

  Hi Aznie.

  Thank you so much for confirmin and suggesting a solution.

  I read this documentation.

  then, I executed below source code.

  import pyrealsense2 as rs
  import numpy as np
  
  
  def initialize_camera():
      p = rs.pipeline()
      conf = rs.config()
      conf.enable_stream(rs.stream.accel)
      conf.enable_stream(rs.stream.gyro)
      prof = p.start(conf)
      return p
      
  
  
  def gyro_data(gyro):
      return np.asarray([gyro.x, gyro.y, gyro.z])
  
  
  def accel_data(accel):
      return np.asarray([accel.x, accel.y, accel.z])
  
  p = initialize_camera()
  
  try:
      while True:
          f = p.wait_for_frames()
          accel = accel_data(f[0].as_motion_frame().get_motion_data())
          gyro = gyro_data(f[1].as_motion_frame().get_motion_data())
          print("accelerometer: ", accel)
          print("gyro: ", gyro)
  
  finally:
      p.stop() 

  However, I got error code in line 26 (f = p.wait_for_frames()).

  Error message: Frame didn't arrive within 5000.

  Please tell me what else I need to check.
  Thank you.

  Hi Kenji Yasuda,
  The python case looks fine and it should work. It must be a system issue. Try to run the code from another PC.
