Failed to install USD Chat in Isaac Sim

Detailed Description

I’m trying to install the “Chat USD” extension in Isaac Sim and get two errors:

1. The extension fails to install correctly “Failed to solve extension dependency” error
2. For some reason I can still open the Chat USD window in Isaac Sim UI, but when I try to use it it just reports “Missing API Key”

Steps to Reproduce

1. Open the Extensions window
2. Search for Chat USD
3. click to install the extension. The fist time it seems to install correctly, the install switch turns green. But then if I reopen the Extensions window I see the error message.

Error Messages

“Failed to solve extension dependency”

Follow this video. You need to get an API key from our developer website at www.build.nvidia.com

Thanks! I have a key now, but where/how do i use it? The video just show’s usage of Chat USD but nothing with keys. There’s no mention of keys in the plugin description or the USD Chat page: Chat USD Overview — omni.ai.chat_usd.bundle

I tried following this and added an env var:

Get Started — Synthetic Data Generation with Generative AI Reference Workflow

And restarted Isaac sim, but i get the same errors.

OK you have to go to the extension manager find the extension again and then you have to edit the toml file of the extension. To do this, there is a little notepad editor icon on the far right. Click that and I’ll open up the Toml file for the extension. In there, it literally says “insert your API key”. Just paste in your API key and save the file. Then restart the application.
