[Python] Python async issue with PhaseMap package

PhaseMap is a python package I am trying to use, but the minimal working example in the tutorial isn't working:

import phasemap as pm

def phase(pos):
x, y = pos
return int(x**2 + y**2 < 1)

res = pm.run(
phase,
limits=[(-1, 1), (-1, 1)],
mesh=3,
)


When I run this code (on Python 3.11.9), the following error is raised:

File ~/Desktop/repos/non_linear_topological_invariants/nonlinear_topological_invariants/lib/python3.11/site-packages/phasemap-1.0.0-py3.11.egg/phasemap/_run.py:103, in run(fct, limits, mesh, num_steps, all_corners, init_result, save_file, load, load_quiet, serializer, save_interval)
90 else:
91 init_points = None
93 return _RunImpl(
94 fct=fct,
95 limits=limits,
96 mesh=mesh,
97 num_steps=num_steps,
98 all_corners=all_corners,

632 new_task = not futures.isfuture(future)
633 future = tasks.ensure_future(future, loop=self)

590 if events._get_running_loop() is not None:
591 raise RuntimeError(
592 'Cannot run the event loop while another loop is running')

RuntimeError: This event loop is already running


This seems like a straightforward issue with the implementation of the asyncio library, but I don't know how to fix it. Is there a straightforward fix to this package that will solve the issue?

Thanks!
