Error getting to run an example

[emrecemal]

Hello,

I freshly created a conda environment, and install pinocchio, and I wanted to run this example: examples/cassie-simulation.py However, I'm getting this error:

Traceback (most recent call last):
  File "/home/emrecemal/git_ws/check_cassie/main.py", line 30, in <module>
    robot = pinocchio.RobotWrapper.BuildFromSDF(

    robot.initFromSDF(

  File "/home/emrecemal/git_ws/check_cassie/.venv/lib/python3.10/site-packages/pinocchio/shortcuts.py", line 113, in buildModelsFromSdf
    model, constraint_models = pin.buildModelFromSdf(
AttributeError: module 'pinocchio.pinocchio_pywrap_default' has no attribute 'buildModelFromSdf'. Did you mean: 'buildModelFromUrdf'?

How can I solve it?

Hello,

If you want Sdf support, you need to compile pinocchio from source, because it's not included in the conda package.

Hello @emrecemal,

Since Pinocchio 3.3.0, the conda package is build with SDF support.
