isaaclab 命令：train/play/benchmarkProxyArray 零拷贝 .torch/.warp 双后端访问为什么重要 为具身智能训练与评测提供单一 CLI、多物理后端和零拷贝数据，减少环境切换与数据搬运成本，需评估迁移影响。适合 具身智能仿真训练与评测工程师，尤其 Isaac Sim / RSL-RL 用户。
isaaclab CLI：train/play/benchmark，替代各库专用脚本。ProxyArray 数据容器，提供 .torch/.warp 零拷贝访问。--viz 后端：newton_gl、newton_rtx、kit、viser、rerun。--checkpoint，支持 latest/best/pretrained/路径。$ git clone --branch release/3.0.0 https://github.com/isaac-sim/IsaacLab.git
$ cd IsaacLab && uv run isaaclab train --rl_library rsl_rl --task Isaac-Cartpole physics=newton_mjwarp --viz newton_gl
$ uv run --extra ov isaaclab train --rl_library rsl_rl --task Isaac-Cartpole-Camera-Direct physics=ovphysx renderer=ovrtx presets=rgb --viz newton_gl
Isaac Lab 3.0 早期访问已就绪。 Isaac Lab 3.0 为 Isaac Lab 的下一代机器人学习奠定了基础：跨多个物理、渲染与可视化后端使用同一套任务 API；免 Kit 执行；Warp 原生数据路径；从安装到训练、评估与部署的统一工作流。
本版本基于 Isaac Sim 6.1、Python 3.12、PyTorch 2.11、NVIDIA Warp 1.16 和 Newton 1.5.2 构建。
[!NOTE] 早期访问状态 Isaac Lab 3.0 的架构与功能集已可供用户在其上构建。从早期访问到正式发布（GA），
release/3.0.0分支将只关注缺陷修复、稳定性、兼容性与文档改进。正式发布预计在 2026 年 10 月底。 我们鼓励你从现在开始迁移、训练与测试——并告诉我们你的发现。
安装 uv，克隆早期访问分支，并启动免 Kit 的 Newton 工作流：
bash git clone --branch release/3.0.0 https://github.com/isaac-sim/IsaacLab.git cd IsaacLab
uv run isaaclab train
--rl_library rsl_rl
--task Isaac-Cartpole
physics=newton_mjwarp
--viz newton_gl
如需完全免 Kit 的 PhysX 与 RTX 渲染工作流，请使用 OVPhysX 与 OVRTX 后端。ov ext
Isaac Lab 3.0 Early Access is ready.
Isaac Lab 3.0 establishes the foundation for the next generation of robot learning in Isaac Lab: one task API across multiple physics, rendering, and visualization backends; kit-less execution; Warp-native data paths; and unified workflows from installation through training, evaluation, and deployment.
This release is built for Isaac Sim 6.1, Python 3.12, PyTorch 2.11, NVIDIA Warp 1.16, and Newton 1.5.2.
[!NOTE] Early Access status
The architecture and feature set for Isaac Lab 3.0 are ready for users to build on. From Early Access to General Availability, the
release/3.0.0branch will focus only on bug fixes, stability, compatibility, and documentation improvements. General Availability is targeted toward the end of October 2026.We encourage you to start migrating, training, and testing now—and to tell us what you find.
Install uv, clone the Early Access branch, and launch a kit-less Newton workflow:
git clone --branch release/3.0.0 https://github.com/isaac-sim/IsaacLab.git
cd IsaacLab
uv run isaaclab train \
--rl_library rsl_rl \
--task Isaac-Cartpole \
physics=newton_mjwarp \
--viz newton_gl
For a fully kit-less PhysX and RTX rendering workflow, use OVPhysX and OVRTX backends. The ov extra installs both optional runtimes; Isaac Sim is not installed or launched:
uv run --extra …
