[Pw_forum] Error while running excises

[Mohammed Ghadiyali]

Hello, 
I 'm currently tying to learning Quantum Espresso using tutorials give but I 'm not able to run the excises. I 'm constantly getting this error

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%     Error in routine readpp (2):     file /usr/share/espresso/pseudo/Si.pbe-rrkj.UPF not found %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     stopping ...--------------------------------------------------------------------------MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode 0.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.You may or may not see output from other processes, depending onexactly when Open MPI kills them.

Can some one help me out
Thank You,Ghadiyali Mohammed Kader
