• Install the Dev Containers pre-release extension (0.265.0-pre-release or later).
• With nvidia GPU (@connor4312):
  • Have a devcontainer.json with "hostRequirements"."gpu" and verify that the devcontainer comes with GPU enabled/disabled depending on the config.
• Without Nvidia GPU:
  • Have a devcontainer.json with "hostRequirements"."gpu" and verify that the Dev Containers extension warns about the GPU not being available when one is required depending on the config.
• Verify that there is IntelliSense for the "hostRequirements"."gpu" property in the devcontainer.json and its description makes sense.

This doesn't seem to work, despite the GPU being detected when running the CUDA "hello world" container:

Here's my docker info:

We check the docker info for Runtimes?.nvidia?.path === 'nvidia-container-runtime' to determine if a GPU is available. Not sure why that is missing in your case, but the sample still works. @chris-major-improbable Do you have additional insights into when the GPU is listed in the runtimes and when not?
