GUI doesn't show when start to simulate

[BoyuanTang331]

when I try to generate more than one scene to simulate, I find this problem many times that the GUI doesn't show and wait for long time the code won't stop

why this problem happened and how can I avoid it?

Thanks

What exactly do you mean by "generate more than one scene"?

[BoyuanTang331]

just like I open two custom_scense.py and running these two file at same time, use two file to simulate.

I deleted the repo and downloaded it once again it will solved before, I guess it may caused by the cache problem. It is very weird

This time I wrote this new code on a scratch file, at beginning it can run and simulate and also show the GUI window correctly, but once I changed some parameters it comes out this problem

I move this scratch file to the repo dictionary, the code runs temporal

Can you try to run it without using cached files? There is a command line option "--no-cache".
