Installation

Follow this guide to install UV.

Running it

To run the entrypoint, run the following command.

 uv run -m semistaticsim.groundtruth.main

You can set the target amount of simulation time to collect as well as the scan size. The bigger the scan size, the higher the RAM usage and jitting time, but it has the potential to go faster if you want to collect a lot of simulation time.

After collecting the data, plot the groundtruth of the first pickupable across all its valid receptacles:

uv run -m semistaticsim.groundtruth.viz

To run the ai2thor simulation, you can use

 uv run -m semistaticsim.keyboardcontrol.main_skillsim

On the cluster

Installation:

module load anaconda/3
conda create -n sss -c conda-forge python=3.12 libvulkan1 uv
rm -rf ./generated_data && mkdir -p $SCRATCH/sss/generated_data && ln -s $SCRATCH/sss/generated_data ./generated_data

Single job on an interactive compute node:

module load anaconda/3 && conda activate sss
export LD_LIBRARY_PATH=$CONDA_PREFIX/lib:$LD_LIBRARY_PATH
# uv run -m semistaticsim.[groundtruth.main | keyboardcontro.main_skillsim] [hydra overrides]

Multirun:

For both GT and Rendering, there's a lot of SLURM setup at first, and then the last few args will be actual hydra overrides. Note: if you have loaded anaconda/3, you WILL break the multirun. You need to unload all modules, and only load python/3.10 and launch using uv. The anaconda/3 module will be automatically loaded by the scripts themselves, inside semistaticsim/spoof_hydra.py.

NOTE: This is set to launch on partition main. On the Mila cluster, this means that only 1 batch of 4 tasks will run at once. Swap to partition long if you wish for massive parallelism (but less priority).

Groundtruth:

module load python/3.10
uv run -m semistaticsim.groundtruth.main --multirun hydra/launcher=sbatch +hydra/sweep=sbatch hydra.launcher._target_=hydra_plugins.packed_launcher.packedlauncher.SlurmLauncher hydra.launcher.tasks_per_node=4 +hydra.launcher.timeout_min=59 hydra.launcher.gres=gpu:1 +hydra.launcher.constraint='40gb|48gb'  hydra.launcher.cpus_per_task=2 hydra.launcher.mem_gb=40 hydra.launcher.array_parallelism=300 hydra.launcher.partition=main hydra.launcher.name=SSS_GT procthor_index=range\(0,8\)

Rendering:

module load python/3.10
uv run -m semistaticsim.keyboardcontrol.main_skillsim --multirun hydra/launcher=sbatch +hydra/sweep=sbatch hydra.launcher._target_=hydra_plugins.packed_launcher.packedlauncher.SlurmLauncher hydra.launcher.tasks_per_node=4 +hydra.launcher.timeout_min=59 hydra.launcher.gres=gpu:1 +hydra.launcher.constraint='40gb|48gb'  hydra.launcher.cpus_per_task=2 hydra.launcher.mem_gb=40 hydra.launcher.array_parallelism=300 hydra.launcher.partition=main hydra.launcher.name=SSS_PRIV mode=auto index=range\(0,4\)

How-to

Features are based around varying the level of scene-to-scene semantic transfer. Every simulator step, some dt time elapses. When the duration_left reaches 0, the transition model selects the next receptacle that the object will transition to. Then, the duration model sampels the amount of tiem that the objet will spend in that new receptacle.

Duration model:

1. even is "evenly spread duration of all steps"
2. instant is "spend NO time at this place, immediately transition at the next step" (this is what flowmaps currently has in your 2D simulator)
3. deterministic is "randomly split the day among all steps"
4. gaussian is the same as deterministic with some gaussian noise

Transition model:

1. "fixed_canonical": object cycles down a list of fixed receptacles
2. "fixed_0.1_0.9": object has 10% chance of staying put, 90% chance of going to the next receptacle in cycle (this is what the 2D flowmaps simulator has)
3. "uniform_no_diag": fully uniform transition matrix
4. "uniform_full": fully uniform transition matrix
5. "location_weighted_uniform_no_diag": uniform transition matrix weighted by the ProcThor receptacle prior
6. "location_weighted_uniform_full": uniform transition matrix weighted by the ProcThor receptacle prior

Preliminary scan experiments

1. SCANSIZE 10: ~33.5 it/s : 335 steps/s
2. 100 : 33 : 3300

1000 : eta 50min

1000 : cpu: 3s/it; cuda is same!
