Anybody has any idea to solve this problem kindly reply.

Have a read thru this thread.

yes i read thru this thread. Do u have any idea ?

Seems to be permissions issue with gpio, might have better luck in the RPI forums, although no idea how often it is used there.

My guess is gpio16 does not exist. remove it
