QMutex:destroying locked mutex #10

Open linjuechu opened 2 years ago

linjuechu commented 2 years ago

I'm replicating https://github.com/andyzeng/visual-pushing-grasping. that's your project (use the code) on github.As recommended, I installed the Ubuntu Dual System(Ubuntu18.04). Now I have a problem--QMutex:destroying locked mutex,like the picture),this error occurs when coppeliasim is run (CoppeliaSim_Edu_V4_1_0_Ubuntu18_04). This problem did not occur during the first 200 training iterations,but use the "snapshot-backup.reinforcement.pth",this is where the problem arises. I don't know if you know what the reason for this is or what the solution is.

Hello linjuechu,

Could you post the image again? It's not visible.

So this is your CoppeliaSim terminal, I assume it is terminated and you got this output, however, I see in the back that Coppeliasim Is running, so I am not sure what is happening here. Maybe you can give more info from the terminal, also what you get on the client side.

Cheers

At the same time as the error was reported, my coppeliasim automatically exited,Includes a simulation page.If I don't do “./coppeliasim.sh" again, the training breaks and shows that not connection simlation(coppeliasim), so I started coppeliasim again,and execute python programs at the same time. So the simulation platform page you see is what I opened again. If you need more information to determine the cause of the problem, I can tell you more about this next time this happens. Thank you!

I tried to run it again under the ubuntu system，hopefully it would work perfectly, but the same thing happens,I saved more pictures and hope it will help in solving the problem and finding out the cause.First there were several successful iterations，like Figure 1,then there was a software flashback，the terminal is displayed as shown in Figure 2,I do not open the coppeliasim again,the terminal page stops to remain at Figure 3 c090f13f7bcac2d110e83a39a705e50 644e7cb47ceb5be93ff7e55d4acfdb8 23e77a1ffe46091fc01b3d98613606f

This seems to be CoppeliaSim related. Maybe you can have a look at this https://forum.coppeliarobotics.com/viewtopic.php?t=7921 Or ask in the CoppeliaSim Forum.

Cheers
