[Pw_forum] Question on epsilon.x

[mohsen modaresi]

Dear Andrea thanks for your answers, they were helpful for me.
I faced with a new question, can any one help me, please?:
I run a PW.X with this input file
 &control
    calculation = 'scf'
    restart_mode='from_scratch',
    prefix='silicon',
    tstress = .true.
    tprnfor = .true.
    pseudo_dir = '/home/nano/Desktop/esp/psudo'
    outdir='/home/nano/Desktop/esp/out/si'
 /
 &system
    ibrav=  2, celldm(1) =10.20, nat=  2, ntyp= 1,
    ecutwfc =70.0,
 /
 &electrons
    mixing_mode = 'plain'
    mixing_beta = 0.7
    conv_thr =  1.0d-8
 /
ATOMIC_SPECIES

 Si 0.00 0.00 0.00
 Si 0.25 0.25 0.25
K_POINTS

    0.1250000  0.1250000  0.1250000   1.00
    0.1250000  0.1250000  0.3750000   3.00
    0.1250000  0.1250000  0.6250000   3.00
    0.1250000  0.1250000  0.8750000   3.00
    0.1250000  0.3750000  0.3750000   3.00
    0.1250000  0.3750000  0.6250000   6.00
    0.1250000  0.3750000  0.8750000   6.00
    0.1250000  0.6250000  0.6250000   3.00
    0.3750000  0.3750000  0.3750000   1.00
    0.3750000  0.3750000  0.6250000   3.00
Every things done well, But when i run epsilon.x with this input file:
&inputpp
    outdir= '/home/nano/Desktop/esp/out/si'
   prefix='silicon',
   calculation= 'eps',
 /
 &energy_grid
    smeartype='gauss'
    intersmear=0.1
    intrasmear=0.1
    wmax=30.0d0
    wmin=0.0d0
    nw=100
    shift=0.0d0
 /

I get this eror:

and in the command prompt it print: "application called

Where is the problem?
Thanks for your reply.
