@Hugo and @guillaumeparan,
Sorry for the late reply and thank you for your help! Good news is it works! I found that windows found the wrong directory for Qt5Core, which cause GUI failed to be imported. And now it works!!! Thank you very much for your help!

Hi, @Hugo,
Unfortunately, I did not solve the problem. I actually don’t understand what you mean PYTHONPACKAGE. Is PYTHONPACKAGE a system environmental variable or you mean python package related variable like PYTHON_ROOT or PYTHONPATH. Anyway, I did try to create variable called PYTHONPACKAGE linking to SofaPython3 site-packages and python site-packages. But it does not work.

I want to share the variables I set to make sure if there is some problems.

PYTHON_ROOT: C:\Users\user\AppData\Local\Programs\Python\Python37
 PYTHONPATH: C:\SOFA\SOFA_v21.06.01_Win64\plugins\SofaPython3\lib\python3\site-packages
 SOFA_ROOT: C:\SOFA\SOFA_v21.06.01_Win64
 Path: %PYTHON_ROOT%;%PYTHON_ROOT%\DLLs;%PYTHON_ROOT%\Lib;%SOFA_ROOT%\bin;%SOFA_ROOT%;C:\Users\user\AppData\Local\Programs\Python\Python37\Scripts 

With above settings, I can successfully run runSofa with Sofapython3 in cmd which means sofa_root\bin is successfully set.

C:\Users\user>runSofa

Hi, @Hugo,

I met the same problem using v21.06.01, but getObject() function still not work. I met the error

def createScene(root):
    model = root.addChild("model")
    model.addObject("RegularGridTopology", name = "grid",min = "-5 -5 0", max = "5 5 40", n = "3 3 10")
    print(LRmodel.getObject("grid"))

I run in python, error
[ERROR] [SofaRuntime] AttributeError: Missing attribute: getObject
in runSofa
[ERROR] [SofaPython3::SceneLoader] AttributeError: Missing attribute: getObject

Oh, the image link broke, the path included site-packages in SofaPython3 and other DLLs or Lib of python. I can import Sofa.Simulation and other components in this package except Gui and I can use runSofa, too.

by the way how to actually put an image, I actually put the image in my goole drive and share the link in this post, but it breaks

Hi, @Hugo,
Thanks you for your advice, I read the examples about writing data and successfully record states by using monitor or VtkExamples, but I have one question left that I do not know how to access data field in python. I did not find related examples in sofaPython3 and sofa. Thanks very much for your help!
