Cannot download a large zip file of assets of Isaac-sim 2022.1.1 in local storage

Omniverse Isaac Sim

Hello members of NVIDIA forums,

I have a question about downloading assets of Isaac-sim 2022.1.1 in my local PC.

I installed isaac-sim 2022.1.1 by following the official documentation.
https://docs.omniverse.nvidia.com/app_isaacsim/app_isaacsim/install_basic.html

I confirmed the followings:

  • Isaac-sim works normally (I did basic tutorial in the official documentation).
  • localhost:3080 (system monitor) showed running services. (All services run normally.)
  • localhost:8080 (web UI of nucleus) showed assets of Isaac-sim.
  • Omniverse Navigator showed assets of Issac-sim.
    • The navigator was launched from “Nucleus Navigator” in the side bar of Omniverse Launcher.

Then, I tried to download the assets of Isaac-sim 2022.1.1 by using web UI of nucleus or Omniverse Navigator.
However, I could not download the assets in my local PC.

[When I used Omnivrse Navigator to download the assets]
I could download a single file or a small zip file.
However, If I tried to download a large zip file (about more than 1.35MB), the process stops at the point of 1.35MB.
I waited the process in about 1h, the process was same.

  • The example of the single file: omniverse://127.0.0.1/NVIDIA/Assets/Isaac/2022.1/Isaac/Environments/Hospital/hospital.usd
  • The example of the small zip file: omniverse://127.0.0.1/NVIDIA/Assets/Isaac/2022.1/Isaac/Environments/Grid/.thumbs/256x256/
  • The example of the large zip file: omniverse://127.0.0.1/NVIDIA/Assets/Isaac/2022.1/Isaac/Environments/Grid/

When I failed to download, the “logs” tab in localhost:3080 (I selected service “Nucleus”) shows the following errors:

[When I used web UI of nucleus to download the assets]
I could not download a single file, a small zip file and a large zip file.

[My environments]

  • ubuntu 18.04
  • using proxy server
    • I checked that I can access internet. Also I checked firewall settings.
    • I use the following command for launching omniverse launcher: ./omniverse-launcher-linux.AppImage --proxy-server=proxy ip:port

[Other info.]

  • When I try to watch the asset from “Content” tab in Isaac-sim GUI, the terminal shows the error:

Is something wrong in my setup?

Hi.
First step is to test that you can open any file from the /NVIDIA/Assets/Isaac/2022.1/Isaac folder in your local Nucleus into Isaac Sim.
Next, do a right-click copy of the /NVIDIA/Assets/Isaac/2022.1/Isaac folder and right-click paste on any local folder like /Library. This may take some time.
You should be able to then zip up and download this /Library/Isaac folder.

Hi, Thank you for kind introduction.
Unfortunately, I couldn’t open the assets.

First step is to test that you can open any file from the /NVIDIA/Assets/Isaac/2022.1/Isaac folder in your local Nucleus into Isaac Sim.

I tried open a file from “open” operation of “File” tab in Isaac Sim GUI.
The operation shows the “Opening a Read Only File” window. Thus I selected “Open Original File”.
However, the GUI said, “Failed to open stage simple_room.usd. Please check console for error.”.

Also, the errors in the console are following:

It looks like you may have a firewall that is restricting access to the public S3 bucket or an issue with your Nucleus install.
What is the output of this command in your terminal?

curl http://omniverse-content-production.s3-us-west-2.amazonaws.com/Assets/Isaac/2022.1/Isaac/Materials/Isaac/nv_green.mdl

Thank you for your reply.
The output of this command is following:

mdl 1.4;
import df::;
import base::;
import math::;
import state::;
import anno::;
import tex::;
import OmniPBR::OmniPBR;

export material nv_green(*) = OmniPBR::OmniPBR(
diffuse_color_constant: color(0.181164,0.48515,0),
emissive_color: color(0,0,0),
enable_emission: true,
uv_space_index: 0
);

That looks good.
Are you able to copy the assets from /NVIDIA to another folder in your local Nucleus?

Hi,
Thank you for your check.
I failed to copy the assets from /NVIDIA to another folder in my local Nucleus.

I tried to copy a single USD file to the parent directory by using the process written in your previous reply.
When I tied to copy, the Isaac-sim UI showed a small popup of ERROR_ACCESS_DENIED.

copy from: omniverse://localhost/NVIDIA/Assets/Isaac/2022.1/Isaac/Environments/Simple_Room/simple_room.usd
to: omniverse://localhost/NVIDIA/Assets/Isaac/2022.1/Isaac/Environments/simple_room.usd

The omniverse://localhost/NVIDIA/* folder is a mount and is read-only.
Try creating a folder omniverse://localhost/Library/Temp and copy to it.

11

Hi,
I’m sorry for the late reply.
I could copy some assets in omniverse://localhost/NVIDIA/* folder to mniverse://localhost/Library/Temp.

copied assets:
omniverse://localhost/NVIDIA/Assets/Isaac/2022.1/Isaac/Props/YCB/
omniverse://localhost/NVIDIA/Assets/Isaac/2022.1/Isaac/Environments/Simple_Room/Props
omniverse://localhost/NVIDIA/Assets/Isaac/2022.1/Isaac/Environments/Simple_Room/Props/simple_room.usd

You may need to copy additional files if there are missing textures.
I would recommend copying the entire folder from
omniverse://localhost/NVIDIA/Assets/Isaac/2022.1/Isaac to omniverse://localhost/Isaac if you have the space.
Some files in the Isaac folder do have a relative dependency to the …/NVIDIA folder.
