NVIDIA Isaac Sim
What is Isaac Sim?
Isaac Sim is NVIDIA's robotics simulation platform built on their Omniverse framework. Here's a quick overview: What it is: A high-fidelity, GPU-accelerated robot simulator that lets you design, test, and train robots in photorealistic virtual environments before deploying to real hardware.
Key features:
- Photorealistic rendering via ray tracing/path tracing, useful for generating synthetic training data
- Physics simulation powered by PhysX 5, supporting rigid bodies, articulations, deformables, and fluids
- ROS/ROS2 integration — bridges for direct sim-to-real transfer of control code
- Sensor simulation — cameras, LiDAR, IMUs, depth sensors with realistic noise models
- Python/OmniGraph scripting for automation and custom workflows
Note
Installing Isaac Sim with pip requires GLIBC 2.34+ version compatibility. To check the GLIBC version on your system, use command ldd --version.
Note
On Windows with CUDA 12, the GPU driver version 552.86 is required. Also, on Windows, it may be necessary to enable long path support to avoid installation errors due to OS limitations.
Open your PowerShell as an administrator and run the following command:
New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem" -Name "LongPathsEnabled" -Value 1 -PropertyType DWORD -Force
Disable IOMMU
- Verify that IOMMU is disabled if the two commands below do not print any outputs:
$ sudo dmesg | grep -e DMAR -e IOMMU

Installing Isaac Sim (5.1 or later)
Create Conda Environment
$ conda create -n isaac python=3.11
$ conda activate isaac
$ python -m pip install --upgrade pip
Before installing Isaac Sim, ensure the latest pip version is installed. To update pip, run
$ pip install --upgrade pip
Then, install the Isaac Sim packages.
$ pip install "isaacsim[all,extscache]==5.1.0" --extra-index-url https://pypi.nvidia.com
Install a CUDA-enabled PyTorch build that matches your system architecture:
$ pip install -U torch==2.7.0 torchvision==0.22.0 --index-url https://download.pytorch.org/whl/cu128
Verifying the Isaac Sim installation
- Make sure that your virtual environment is activated (if applicable)
- Check that the simulator runs as expected:
# note: you can pass the argument "--help" to see all arguments possible.
$ isaacsim
It’s also possible to run with a specific experience file, run:
# experience files can be absolute path, or relative path searched in isaacsim/apps or omni/apps
$ isaacsim isaacsim.exp.full.kit
Note
When running Isaac Sim for the first time, all dependent extensions will be pulled from the registry. This process can take upwards of 10 minutes and is required on the first run of each experience file. Once the extensions are pulled, consecutive runs using the same experience file will use the cached extensions.
Note
The first run will prompt users to accept the NVIDIA Software License Agreement. To accept the EULA, reply Yes when prompted with the below message:
By installing or using Isaac Sim, I agree to the terms of NVIDIA SOFTWARE LICENSE AGREEMENT (EULA) in https://www.nvidia.com/en-us/agreements/enterprise-software/nvidia-software-license-agreement
Do you accept the EULA? (Yes/No): Yes
