Module openpnm has no attribute geometry

[baelow]

when I ran code of example, it shows error (AttributeError: module 'openpnm' has no attribute 'geometry') again and again. It makes me very confused. Could dear professor help me deal with this problem? Thank you.
The following is details:

import openpnm as op
Lc = 1e-4
Nx, Ny, Nz = (10, 10, 10)
pn = op.network.Cubic(shape=[Nx, Ny, Nz], spacing=Lc)
geo = op.geometry.SpheresAndCylinders(network=pn, pores=pn.Ps, throats=pn.Ts)
Hg = op.phases.Mercury(network=pn)
phys = op.physics.Standard(network=pn, phase=Hg, geometry=geo)
mip = op.algorithms.Porosimetry(network=pn, phase=Hg)
mip.set_inlets(pores=pn.pores(['left', 'right', 'top', 'bottom']))
mip.run()

ipython-input-3-11dabb12c30d in module
      7 # Generate network, geometry, phase, and physics
      8 pn = op.network.Cubic(shape=[Nx, Ny, Nz], spacing=Lc)
----> 9 geo = op.geometry.SpheresAndCylinders(network=pn, pores=pn.Ps, throats=pn.Ts)
     10 Hg = op.phases.Mercury(network=pn)
     11 phys = op.physics.Standard(network=pn, phase=Hg, geometry=geo)

AttributeError: module 'openpnm' has no attribute 'geometry'

BUT I CAN RUN THESE CODE WITHOUT ANY ERROR:

import openpnm as op
import numpy as np
import matplotlib.pyplot as plt
op.visualization.set_mpl_style()
pn = op.network.Cubic(shape=[4, 4, 4], spacing=1e-5)
ax = op.visualization.plot_coordinates(pn)
ax = op.visualization.plot_connections(pn, ax=ax)

WHAT I TRIED:

• I checked my version-- '3.1.1'
• I reinstall by conda install -c conda-forge openpnm serials times, but it still shows this type error.
• I uninstall by conda remove openpnm and then install dev version from github, --The hard (but correct) way, but it shows another error. -- DLL error (I uesed python 3.8).
• I have tried another env conda create -n foropenpnm, and switched to this env, same error as before (module 'openpnm' has no attribute 'geometry') .python version = 3.8 or 3.9, same problem.
• I used pycharm and Spyder IDE，shows same error.

Now I donnot konw how to do nexr, hope you can help me. Thank you a lot.

You are using the latest version of OpenPNM, but are trying to run an old script. I have written a short post on what is different in V3 and why here

I am very ecstatic to get your reply. 😆 I got it !!. Thank you again professor 👍
