The template below is mostly useful for bug reports and support questions. Feel free to remove anything which doesn't apply to you and add more information where it makes sense.

1. Issue or feature description

Currently, many large language models require several Gi of video memory. Therefore, in order to simplify user settings, we add a parameter to convert the Gi of video memory filled in by the user into Mb of video memory.

2. Steps to reproduce the issue

3. Information to attach (optional if deemed irrelevant)

Common error checking:

• The output of nvidia-smi -a on your host
• Your docker or containerd configuration file (e.g: /etc/docker/daemon.json)
• The vgpu-device-plugin container logs
• The vgpu-scheduler container logs
• The kubelet logs on the node (e.g: sudo journalctl -r -u kubelet)

Additional information that might help better understand your environment and reproduce the bug:

• Docker version from docker version
• Docker command, image and tag used
• Kernel version from uname -a
• Any relevant kernel output lines from dmesg
