When I follow the polymetis usage page and run the script for simulation mode launch_robot.py robot_client=bullet_sim use_real_time=false gui=[true|false]
I get the following error

Description
When I follow the polymetis usage page and run the script for simulation mode
launch_robot.py robot_client=bullet_sim use_real_time=false gui=[true|false]
I get the following errorAfter checking around, simply replacing the config values in
bullet_sim.yaml
line 16-19 (default_Kq
etc) https://github.com/facebookresearch/fairo/blob/0a01a7fa7a7c65b2f9a3aebf5e79040940daf9d2/polymetis/polymetis/conf/robot_client/bullet_sim.yaml#L16 with that ofempty_statistics_client.yaml
values worked. Specifying those value at runtime like thebullet_sim.yaml
file seems to be (intended to?) used, likeErrors out that
default_Kq
is not defined in hydra, while following workCurrent Behavior
Currently the code (graciously) crashes.
Expected Behavior
Supposed to run the simulation server, probably with some appropriate default_K values? (I assume those are PID controller gains?)
Steps to reproduce
micromamba
change the following line fromconda list
tomicromamba list
in this file https://github.com/facebookresearch/fairo/blob/0a01a7fa7a7c65b2f9a3aebf5e79040940daf9d2/polymetis/polymetis/python/polymetis/_version.py#L11 at your install location. (maybe supporting micromamba should also be raised as an issue?)launch_robot.py robot_client=bullet_sim use_real_time=false gui=[true|false]
