Topic Description

Detailed Description

Trying to install Isaac Sim via pip and realised that the pip installation is broken. I would prefer to install through pip as I want to install isaac sim as part of a larger Dockerfile with a different base image.

Steps to Reproduce

Create a virtual environment: python3.10 -m venv test
Source the virtual environment: source test/bin/activate
Install isaac sim through pip: pip install isaacsim[all]==4.5.0 --extra-index-url https://pypi.nvidia.com

I’ve encountered the same problem as you. Have you solved it?

benjaminlwm7983 · June 27, 2025, 6:49am

I haven’t solved it yet. If you use docker and don’t NEED pip installation, the container installation steps from here still works.

995291627 · June 27, 2025, 12:14pm

I meet the same problem, which shows “HTTP Error 404: Not Found”. Did you solve it?

toni.nv · June 27, 2025, 1:21pm

Hi @benjaminlwm7983, @chenjiadragon, @995291627

Thank you for the report.

We are experiencing an issue with the Isaac Sim and Isaac Lab packages in the pypi.nvidia.com Python index.
We are working on restoring them.

alanprado · June 27, 2025, 2:47pm

Hi Toni, is this fix planned for today? Or is there any other way I can install the modules without the pip? Thank you.

toni.nv · June 27, 2025, 2:54pm

Hi @alanprado

We are still working on restoring them. However, I cannot guarantee a solution time.

Meanwhile, you can install Isaac Sim using other ways such as Workstation Installation or the Container Installation.
See Installation — Isaac Sim Documentation for the different ways to install Isaac Sim.

Hello! Has there been any updates to this? I am receiving the same error

Richard3D · June 27, 2025, 10:14pm

We are aware of a tempory issue with installing Isaac Sim 4.5, due to some online assets, going offline. We are addressing this. However, if you are trying to install 4.5 right now, may I suggest ISAAC SIM 5.0 ! Why install the old version ? :-)

GitHub - isaac-sim/IsaacSim: NVIDIA Isaac Sim™ is an open-source application on NVIDIA Omniverse for developing, simulating, and testing AI-driven robots in realistic virtual environments.

scanton · June 27, 2025, 10:18pm

because 5.0 is still in beta and i don’t want to deal with a changing API right now

Richard3D · June 27, 2025, 10:21pm

So if you are in a “current” isaac sim project, why are you re-downloading it? I would still try the new 5.0. We will not break your project. It is hopefully even better.

But either way, we are aware of this temporary situation and it should be resolved asap.

mobina.j · June 29, 2025, 4:13am

On the repo it mentions the minimum requirement for 5.0 is RTX 4080 and with my current RTX 4070 I think it would be better to go with 4.5 version anyway.
Do you have any approximate of the wait time for the fix?

sahil.rajpurkar · June 29, 2025, 1:44pm

I’ve installed Isaac Lab 2.0 inside a Conda environment, and I installed Isaac Sim 5.0 using the instructions from the official NVIDIA page.

Since Isaac Sim 5.0 doesn’t set up a Python environment like earlier versions, how do I connect it with Isaac Lab?

Do I need to set any environment variables in my Conda environment?

Should I move or link Isaac Lab into the Isaac Sim folder?

Is there a recommended way to make Isaac Lab 2.0 work with Isaac Sim 5.0?

Thanks in advance!

Richard3D · July 1, 2025, 2:12am

I appreciate you noting the minimum specs, but you are close. I would still encourage you to try it out as well as 4.5. I am sorry for the recent 4.5 PIP install issues. Let me check on that.

VickNV · July 1, 2025, 8:50pm

The issue has been resolved. Please refer to [RESOLVED] Isaac Sim and Isaac Lab Packages Issue on PyPI - #5 by rthaker.
