Could Z2pack directly calculate the Chern number with first principle
I have considered a system with odd number occupied bands (with SOC
considered), I set the related parameters the similiar way as the Z2
surface=lambda s, t: [ s, t, 0]
num_wann=num_bands= the number of occupied bands (odd)
The error happens in wannier90.wout
> Error: For spinor WF num_wann ust be even
Maybe the intrinsic physic in the Chern number I have not known.
