Failed to replay the trajectory when setting the sim_backend GPU?

[JuilieZ]

I met an issue that the trajectory wont succeed if I set the sim_backend 'GPU' when I replay the traj.
More seriously ,I completey got the wrong trajectory when I inputed(actually even I didn't add the '-b gpu',it didn't make sense ,either):
python -m mani_skill.trajectory.replay_trajectory --traj-path /home/server/.maniskill/demos/PushT-v1/rl/trajectory.none.pd_joint_delta_pos.cuda.h5 --render-mode="rgb_array" --save-video --count 10 -b gpu

I got the similar issue when I was in other tasks(pickup,pushcube,an so on)
Could u tell me the reason caused the problem?Thank u in advance~

I think our trajectory replay converter needs a massive upgrade. Currently there are some bugs with replaying in parallel on the GPU at the moment that needs to be fixed, the issue is tracked here #564
