errors happen when running the example

[nuclear-missile]

I cd the example folder and run examples, they throw different errors

python3 few_shot_rl.py or multi_task_rl.py or rlbench_gym.py or rearrangement_challenge.py

QObject::~QObject: Timers cannot be stopped from another thread

I am sure the copilia and the pyrep are truely installed. I try to run the example in pyrep, it cancorrectly run, but "QObject::~QObject: Timers cannot be stopped from another thread" at the end. I fund it means the python thread finish but copilia not close. in the RLbench examples it can't even begin.

Hello!
I'm having the same problem as you and I can't solve the problemeven though I've tried multiple things.
I would like to get the way to solve the problem if you have it work!
Thank you!
