how to add seed to replicator in isaacsim?

[shiven2001]

Hi, I want to use replicator to generate synthetic data to train my yolo model. But I want to use the randomization of the replicator. How do I add a seed to the randomizer to ensure reproducibility?

To ensure your synthetic data generation is reproducible, you should set a seed for both Python's built-in random library and for Replicator itself at the beginning of your script, as this on https://docs.isaacsim.omniverse.nvidia.com/5.0.0/replicator_tutorials/tutorial_replicator_getting_started.html#custom-randomizations-replicator-graph-and-usd-api:

    random.seed(42)
    rep.set_global_seed(42)
