Some problems during URDF import process

[liuyidesktop]

I successfully imported the URDF file using the pinocchio library in c++ and was able to complete the relevant calculations. The code is as follows. 
pinocchio::Model model;
std::string urdf_filename = "/home/liuyi/Leg_robot/URDF_generate/test.urdf";
pinocchio::JointModelFreeFlyer root_joint; 
pinocchio::urdf::buildModel(urdf_filename, root_joint,model);
pinocchio::Data data(model);

But when I transplanted it to python, I got the following error after importing URDF，I use the command
conda install pinocchio -c conda-forge to install Pinocchio , the version is 2.7.0

model=pinocchio.buildModelsFromUrdf("/home/liuyi/文档/proj_robot/src/macro_arm6/urdf/macro_arm6.urdf")
data= model.createData()

output:
AttributeError: 'tuple' object has no attribute 'createData'

Hi,

Yeah this function actually returns a tuple (it says buildModels plural and returns the Model and at least a GeometryModel object).

The right version to call in Python would be buildModelFromUrdf (no extra s here)

Thank you for your reply, my problem is solved
