Crash When Generating Multiple Rooms

[GavinZhengOI]

Describe the bug

As I mentioned in #326 , Infinigen crashed while generating an indoor scene with multiple rooms containing objects.

Steps to Reproduce

python -m infinigen.datagen.manage_jobs --output_folder outputs/huge_dataset_nooverride \
--num_scenes 5 --pipeline_configs local_256GB.gin monocular.gin blender_gt.gin indoor_background_configs.gin \ 
--pipeline_overrides get_cmd.driver_script='infinigen_examples.generate_indoors' manage_datagen_jobs.num_concurrent=16

This will run tens of hours and then crash.

What version of the code were you using?

v1.8.1

What command did you run?

python -m infinigen.datagen.manage_jobs --output_folder outputs/huge_dataset_nooverride \
--num_scenes 5 --pipeline_configs local_256GB.gin monocular.gin blender_gt.gin indoor_background_configs.gin \ 
--pipeline_overrides get_cmd.driver_script='infinigen_examples.generate_indoors' manage_datagen_jobs.num_concurrent=16

What are your FULL output logs?

If this is your first time running Infinigen, what are the full install logs?**

Not the first time running. If turn on --configs singleroom.gin and --overrides compose_indoors.restrict_single_supported_roomtype=True, it does not lead to a crash.

• RAM (GB): 64GB

Additional context

I suspect this might be a memory leak issue. I noticed that swap usage was over 85%, while memory utilization was only around 50%. I think it's possible that memory is leaking during execution and eventually consuming all available memory. I've just installed Prometheus on my system and started another execution with the same configuration to monitor memory usage. I'll update you once I have the results.

It seems like there are some kind of memory leak. I'm using python -m infinigen.datagen.manage_jobs --output_folder outputs/single_data_test --num_scenes 1 --pipeline_configs local_64GB.gin monocular.gin blender_gt.gin indoor_background_configs.gin --pipeline_overrides get_cmd.driver_script='infinigen_examples.generate_indoors' manage_datagen_jobs.num_concurrent=16 running single job, and it takes more than 55G of ram gradually then crashed.
