Question

Hi, I want to know if it is possible to profile the RAM usage and variables allocations using carb.profiler directly. For now I wrap the scripts with tracemalloc to get detailed information about memory usage but it is not so convenient.

Also, is it normal that _SIM_APP_CFG_TYPES in AppLauncher don't correspond to SimulationApp configuration? I would needed profiler_backend parameter to run tracy in headless mode but it wasn't available as I wasn't able to pass it down to SimulationApp.

Here is a comparison between _SIM_APP_CFG_TYPES and the IsaacSim documentation:
