Blueprints webpage shows as blank with demo content

AI & Data Science NVIDIA Blueprints

Hi,
I tried installing blueprints in my environment, and the installation and demo content startup were successful. However, the webpage shows as blank, and no images are displayed. Has anyone encountered a similar situation?
The kit’s log is in the attached file. I’m not sure why the log shows that it was failed to open the file world_rtwt_Main_v1.usda in /home/ubuntu/usd.

I’ve resolved the issue of the webpage not displaying images by using git-lfs and rebuilding. However, I’m currently encountering another problem where the car in the middle isn’t showing.
Furthermore, I’m curious if the reason is related to the message “NVST_CCE_DISCONNECTED when m_connectionCount 4294967295 != 1” in the second-to-last line of the logs. Although I’m currently connected via NVC and only have one browser view open, does anyone know how to handle this? Thanks.

Hi @frank_liu,

We sometimes see this error when git lfs is not installed on the system prior to cloning the git repo.

Please can you install git lfs https://git-lfs.com/ and try to clone the repo again.

We are working on udpating the documentation to include this as a prerequisite.

Please let us know how you get on!

Best,

Sophie

Hi @sophwats ,
Thank you for your reply.
I’ve resolved the issue of the display not working, and the cause was indeed the “NVST_CCE_DISCONNECTED when m_connectionCount 4294967295 != 1” message.

When that service of the kit is running, it automatically disconnects and cannot be restarted if it determines that the connection count is not equal to 1.

So, the solution was to first bring up the services using Docker Compose, then monitor the kit’s logs to confirm that the system had finished loading, and only then open the webpage, which then displayed correctly.

Is there a way to restart only the livestream-rtc service? It seems that Omniverse is running normally in the background, but after the livestream-rtc service disconnects, it cannot be restarted and requires restarting the entire kit service.

Additionally, I’ve noticed that the aeronim service has issues running on Blackwell architecture GPUs (RTX PRO 6000), and it seems the NumPy version needs to be updated.

Best,

Frank Liu
