AttributeError: 'pymeshlab.pmeshlab.MeshSet' object has no attribute 'snapshot'

[beam-hub]

import pymeshlab as ml
import numpy as np
input_file = 'test.obj'
mesh = ml.MeshSet()
mesh.load_new_mesh(input_file)
color1 = ml.Color(50,50,50,255)
mesh.snapshot(
#imagebackgroundcolor = color1,
#imagewidth = 512,
#imageheight = 512,
imagefilename = 'test.png'
)
I ran into this problem while executing this code, does anyone know how to fix it?
