Errors/Warnings using Replicator Docker image

[bruno.vetter]

I am starting to work with the Replicator Docker image, v1.6.3. I am running the attached script like this on an OVX:
docker run --gpus all --env HTTP_PROXY="$HTTP_PROXY" --env HTTPS_PROXY="$HTTPS_PROXY" -v .:/data omniverse-replicator-cached:1.6.3 --/omni/replicator/script=/data/simulate.py

The simulation generates images and metadata, seemingly correctly, but I get a lot of warnings and errors in the log (see attached file).

For example:

...

2023-04-27 07:38:58 [1,350ms] [Error] [omni.splash.plugin] startupManagerImpl: ISplashScreen interface failed to properly initialize.

Do you know what the cause of these is and whether they are significant?

Thanks for any help

Hi Bruno,

As you noted, Replicator is still producing correct output, so that is a good thing.

Most of these errors are harmless and have to do with issues relating to Omniverse running in a Docker environment. We will file some bug tickets and get these cleaned-up in the future so as not to confuse users with what are or are not serious errors.

If all those errors are without relevance, it’s fine for me.

Thanks
Bruno
