pip install need patch, example fails

Installed this (great!) library via pip. But then on running the example:

from nano_graphrag import GraphRAG, QueryParam

graph_func = GraphRAG(working_dir="./dickens")

with open("./book.txt") as f:
    graph_func.insert(f.read())

I get the following error:

      1 from __future__ import division
      3 from builtins import str, range, object
----> 4 from past.utils import old_div
      6 import autograd.numpy as np
      7 from ._utils import outer_rows

ModuleNotFoundError: No module named 'past'

Seems an issue with graspologic:

pip install future=1.0.0 solves this.
