🐛 Bug Fixes

  • Fixes rendering frame delays. Rendered images now faithfully represent the latest state of the physics scene. We added the flag
    rerender_on_reset in the environment configs to toggle an additional render step when a reset happens. When activated, the images/observation always represent the latest state of the environment, but this also reduces performance.

✈️ Migration Guide

Setting the simulation device into the simulation context

Details

Previously, changing the simulation device to CPU required users to set other simulation parameters (such as disabling GPU physics and GPU pipelines). This made setting up the device appear complex. We now simplify the checks for device directly inside the simulation context, so users only need to specify the device through the configuration object.

Before:

sim_utils.SimulationCfg(device="cpu", use_gpu_pipeline=False, dt=0.01, physx=sim_utils.PhysxCfg(use_gpu=False))

Now:

sim_utils.SimulationCfg(device="cpu", dt=0.01, physx=sim_utils.PhysxCfg())

Setting the simulation device from CLI

Details

Previously, users could specify the device through the command line argument --device_id. However, this made it ambiguous when users wanted to set the device to CPU. Thus, instead of the device ID, users need to specify the device explicitly through the argument --device. The valid options for the device name are:

  • "cpu": runs simulation on CPU
  • "cuda": runs simulation on GPU with device ID at default index
  • "cuda:N": runs simulation on GPU with device ID at N. For instance, "cuda:0" will use device at index "0".

Due to the above change, the command line interaction with some of the scripts has changed.

Before:

./isaaclab.sh -p source/standalone/workflows/sb3/train.py --task Isaac-Cartpole-v0 --headless --cpu

Now:

./isaaclab.sh -p source/standalone/workflows/sb3/train.py --task Isaac-Cartpole-v0 --headless --device cpu

Renaming of teleoperation device CLI in standalone scripts

Details

Since --device is now an argument provided by the AppLauncher, it conflicted with the command-line argument used for specifying the teleoperation-device in some of the standalone scripts. Thus, to fix this conflict, the teleoperation-device now needs to be specified through --teleop_device argument.

Before:

./isaaclab.sh -p source/standalone/environments/teleoperation/teleop_se3_agent.py --task Isaac-Lift-Cube-Franka-IK-Rel-v0 --num_envs 1 --device keyboard

Now:

./isaaclab.sh -p source/standalone/environments/teleoperation/teleop_se3_agent.py --task Isaac-Lift-Cube-Franka-IK-Rel-v0 --num_envs 1 --teleop_device keyboard

Using Python-version of container utility script

Details

The prior container.sh became quite complex as it had many different use cases in one script. For instance, building a docker image for "base" or "ros2", as well as cluster deployment. As more users wanted to have the flexibility to overlay their own docker settings, maintaining this bash script became cumbersome. Hence, we migrated its features into a Python script in this release. Additionally, we split the cluster-related utilities into their own script inside the docker/cluster directory.

We still maintain backward compatibility for container.sh. Internally, it calls the Python script container.py. We request users to use the Python script directly.

Before:

./docker/container.sh start

Now:

./docker/container.py start

Using separate directories for logging videos in RL workflows

Details

Previously, users could record videos during the RL training by specifying the --video flag to the train.py script. The videos would be saved inside the videos directory in the corresponding log directory of the run.

Since many users requested to also be able to record videos while inferencing the policy, recording videos have also been added to the play.py script. Since changing the prefix of the video file names is not possible, the videos from the train and play scripts are saved inside the videos/train and videos/play directories, respectively.

Drops support for the tiled camera with Isaac Sim 4.1

Details

Various fixes have been made to the tiled camera rendering pipeline in Isaac Sim 4.2. This made supporting the tiled camera with Isaac Sim 4.1 difficult. Hence, for the best experience, we advice switching to Isaac Sim 4.2 with this release of Isaac Lab.
