Sir, If I remove nosym and noinv then it gives error like below, so I put
those two

*Input file*

&inputpp
outdir='./out/'
prefix='SiH'
calculation='eps'
/
&energy_grid
smeartype='gauss'
intersmear=0.136d0
intrasmear=0.0d0
wmax=20.0d0
wmin=0.0d0
nw=200
shift=0.0d0
nosym = .TRUE.
noinv = .TRUE.
/
*output file*

     Reading input file...

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%
     Error in routine epsilon (19):
     *non unifrom kpt grid*

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%

     stopping ...
