Here's the one I used:

import vapoursynth as vs

core = vs.get_core()

orig = core.dgdecodenv.DGSource(r'O:\Testclips\test2.dgi', fulldepth=True)
orig = core.f3kdb.Deband(orig, preset="medium", output_depth=10)

clp = core.ffms2.Source(source=r'c:\x265\aq\aqmode3.hevc')
orig = core.resize.Bicubic(orig, width=3840, height=2160, filter_param_a=0, filter_param_b=0.5)
clp = core.resize.Bicubic(clp, width=3840, height=2160, filter_param_a=0, filter_param_b=0.5)

result = core.vmaf.VMAF(orig, clp, model=1, log_path="c:\x265\aq\clp1.log", log_fmt=0, pool=1, ci=True)

result.set_output()

I also noticed that there's no logfile written if I run that one through "vspipe script.vpy ."
