AI Summary: The user is experiencing an issue where the 3D motion captured using Pose2Sim is imported upside down in OpenSim after performing extrinsic camera calibration using manually defined 3D points. The task is to debug this issue, likely involving examination of the coordinate systems used in the calibration process (object_coords_3d) and the orientation of the cameras relative to the scene.

AI Summary: The user is encountering a 'No model specified' error during the Pose2Sim Demonstration Part-1, specifically when running `Pose2Sim.kinematics()`. This indicates a problem with the OpenSim model file path or configuration within the `Config.toml` file used by the `Pose2Sim.kinematics()` function. The task involves debugging the OpenSim model setup to ensure the correct model file is specified for scaling and inverse kinematics.
