Warning: There are no empty bands for at least one kpoint and spin; this may
slow the convergence and/or lead to an inaccurate groundstate.
If this warning persists, you should consider increasing nextra_bands
and/or reducing smearing_width in the param file.
Recommend using nextra_bands of 21 to 33.
