AttributeError: module 'SofaRuntime' has no attribute 'getPythonCallingPoint' #27
Description
Hi,
I'm trying to use SofaPython3 from the conda installation.
I followed the steps and performed the tests suggested, everything works fine.
I then tried a simple python scene and got the error message in the title.
Here is a minimum reproducing example, taken from SofaPython3's documentation :
def createScene(rootNode):
import SofaRuntime
SofaRuntime.importPlugin("Sofa.Component.Visual")
rootNode.addObject("VisualGrid", nbSubdiv=10, size=1000)
return rootNode
Here is the output :
