Error when trying to get my simulation running

I am using Ubuntu 22.04. This is the error I am getting when I am trying to get my simulation running. Any idea how to solve this?

python3 -m motion_imitation.examples.test_env_gui --robot_type=A1 --motor_control_mode=Position --on_rack=True

Based on the output you provided, there doesn't seem to be any clear error message. However, there are some warning messages and notes that appear in the output.

The warning message related to the "Box bound precision lowered by casting to float32" can usually be safely ignored, as it is a Gym library warning and not related to your simulation.

The other message related to the "invalid value encountered in arccos" is a runtime warning that might be related to some computation inside the a1.py script, which is part of your simulation's codebase. This warning may be related to a mathematical error, such as trying to calculate the inverse cosine of a value outside of the range of -1 to 1. You may want to check the code of the a1.py script for any potential issues.

Overall, I would recommend checking the documentation of the motion_imitation package and trying to understand what the test_env_gui script does, as well as the options you are passing to it. Additionally, you may want to check any installation requirements and ensure that all dependencies are properly installed. Finally, you may want to run your simulation with verbose logging enabled to get a better idea of what is happening during the simulation.
