Hello @Zlzxzw1234 let me know if you have specific questions. Thanks
Sorry for interrupting...
I also had the same fail, so let me describe it here.
Execution environment:
- Ubuntu22.04.3 LTS
- conda 23.10.0
- The following commands in "5. test simulation" work correctly.

(I am very impressed with your work.The follow-up "ASAP" is also excellent.)
Thanks @taniguchi-t-nmri for providing more details of the problem!
I tried it on my laptop, and I couldn't reproduce this error. I am using MacBook M1. They were also significantly faster than yours somehow (test_joint_sim.py on 00016 takes 2.83s and run_joint_plan.py on 00016 takes 0.28s).
Let me try later to see if I can reproduce on my linux machine. But anyway, this is a very weird issue that shouldn't happen. I will keep you posted.
I tried on my linux machine and still couldn't replicate this issue. I would suggest a simple fix - just comment out the assertion line and rebuild the simulation using python setup.py install and see if you can still get something reasonable. Otherwise, we may need to delve deep into the code and check why the assertion has failed.
