When remove these lines, the errros still :Fatal error:
Invalid QMMM input: 1 groups 0 basissets and 0 methods;
when put something there, (
QMmethod =rhf;QMbasis =sto-3g),
grompp_a -f pyp.mdp -c pyp.gro -p pyp.top -n pyp.ndx -o pyp_qm.tpr -maxwarn 10
mpirun -np 8 mdrun_a -v -s pyp_qm.tpr

One of the processes started by mpirun has exited with a nonzero exit
code. This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.
PID 11786 failed on node n0 (127.0.0.1) due to signal 11.
how to deal with?

Try to remove these lines, or put something there. The input is ignored, but since strings are used as input (for use in multui-layer oniom), leaving blank causes an error.
