[Wannier] Error: Problem opening input file

[S. D. Wang]

Dear develepers:
I want to calculate bands with wannier90. I fisrt do scf and nscf with
k-point 8 8 1 (my unitcell is 2 dimentioanl). Whtn I do  wannier.x -pp, it
has something wrong like: Error: Problem opening input file.
And my input file of win is:
num_bands       =24 (nbnd=24 in nscf)
num wann        =24
postproc_setup = true
