You do not have the right POTCAR with functional PBE and label Sr_sv in your VASP_PSP_DIR. Paths tried: ['PYMATGEN_POTCAR/POT_GGA_PAW_PBE/POTCAR.Sr_sv', 'PYMATGEN_POTCAR/POT_GGA_PAW_PBE/Sr_sv/POTCAR']

An error occurred when I ran the following code:

from pymatgen.io.vasp.sets import MPHSERelaxSet
from pymatgen.core import Structure

structure = Structure.from_file('SrMoO4.cif')
Relax = MPHSERelaxSet(structure=structure,user_potcar_functional = "PBE" )
Relax.write_input('relax1')


Does anyone know what went wrong?
