how to change numEnvs?

[xuyisen-x]

In task AnymalTerrain, I tried to change the numEnvs from 2048 to 4096, by running the following command:

python scripts/rlgames_train.py task=AnymalTerrain headless=True num_threads=32 num_envs=4096 max_iterations=10 task.sim.physx.gpu_found_lost_pairs_capacity=5194304 task.sim.physx.gpu_found_lost_aggregate_pairs_capacity=71331648 task.sim.physx.gpu_total_aggregate_pairs_capacity=5194304

Then I got Fatal Python error: Segmentation fault at the end of the trainning.

Fatal Python error: Segmentation fault

I must missed something, what should I do? Is there any other configs I must change?

Are you monitoring VRAM? Looks like you may have run out of VRAM for those settings
