Hello all,

I am trying to collect synthetic data through the parallel environments in isaac lab. I have a working code that collects data for me. However, after a few iterations it just gets stuck at this line in terminal:
Starting the simulation. This may take a few seconds. Please wait...

I tried removing and reinstalling conda completely, still the same issue.
I tried running it without wandb, the issue still persists. Any idea as to why this might be happening?
Any help is very appreciated. if anything is required, please just reply here, I will post it asap.

Hi thank you for your response. I found out replacing wandb sweep script with a bash script resolved the issue. The problem was when running the sweep with wandb, it was leaving some traces of the previous run in the gpu or possibly leaving some threads still waiting. And the next iteration never runs. Thank you. I believe posting it here would help someone who might face the same issue.

Thank you
Aditya
