Error response from daemon: Unknown runtime specified nvidia

I am trying to setup a Clara AIAA server by following these instructions:
https://docs.nvidia.com/clara/aiaa/tlt-mi-ai-an-sdk-getting-started/#requirements

I am setting this up on AWS instance p3.2xLarge with ubuntu 16.04
and Docker 19.03

when I get to this step (Running the Container):
sudo docker run -it --rm --ipc=host --net=host --runtime=nvidia --mount
type=bind,source=/your/dataset/location,target=/workspace/data $dockerImage /bin/bash

I get this error:
docker: Error response from daemon: Unknown runtime specified nvidia.

Please help.

Hi,

Please refer to our new documentation here: https://docs.nvidia.com/clara/tlt-mi/clara-train-sdk-v3.0/aiaa/index.html

And seeing your response I am guessing you have not installed the nvidia container toolkit.
Please check the new installation page: https://docs.nvidia.com/clara/tlt-mi/clara-train-sdk-v3.0/nvmidl/installation.html#installation
And follow the steps there for the 3.0 container.

Thanks
