Getting Started#
Prerequisites#
Check the Support Matrix to make sure that you have the supported hardware and software stack.
NGC Authentication#
Generate an API Key#
An NGC API key is required to access NGC resources and a key can be generated here: https://org.ngc.nvidia.com/setup/personal-keys.
When creating an NGC API Personal key, ensure that at least “NGC Catalog” is selected from the “Services Included” dropdown. More Services can be included if this key is to be reused for other purposes.
Note
Personal keys allow you to configure an expiration date, revoke or delete the key using an action button, and rotate the key as needed. For more information about key types, please refer the NGC User Guide.
Export the API Key#
Pass the value of the API key to the docker run command in the next section as the NGC_API_KEY environment variable to download the appropriate models and resources when starting the NIM.
If you are not familiar with how to create the NGC_API_KEY environment variable, the simplest way is to export it in your terminal:
export NGC_API_KEY=<value>
Run one of the following commands to make the key available at startup:
# If using bash
echo "export NGC_API_KEY=<value>" >> ~/.bashrc
# If using zsh
echo "export NGC_API_KEY=<value>" >> ~/.zshrc
Note
Other, more secure options include saving the value in a file, so that you can retrieve with cat $NGC_API_KEY_FILE, or using a password manager.
Docker Login to NGC#
To pull the NIM container image from NGC, first authenticate with the NVIDIA Container Registry with the following command:
echo "$NGC_API_KEY" | docker login nvcr.io --username '$oauthtoken' --password-stdin
Use $oauthtoken as the username and NGC_API_KEY as the password. The $oauthtoken username is a special name that indicates that you will authenticate with an API key and not a user name and password.
Launching the NIM Container#
The following command launches the Maxine Eye Contact NIM container with the gRPC service. Find reference to runtime parameters for the container here
docker run -it --rm --name=maxine-eye-contact-nim \
--net host \
--runtime=nvidia \
--gpus all \
--shm-size=8GB \
-e NGC_API_KEY=$NGC_API_KEY \
-e MAXINE_MAX_CONCURRENCY_PER_GPU=1 \
-e NIM_MANIFEST_PROFILE=7f0287aa-35d0-11ef-9bba-57fc54315ba3 \
-e NIM_HTTP_API_PORT=9000 \
-e NIM_GRPC_API_PORT=50051 \
-p 9000:9000 \
-p 50051:50051 \
nvcr.io/nim/nvidia/maxine-eye-contact:latest
Note
The flag --gpus all is used to assign all available GPUs to the docker container.
To assign specific GPU to the docker container (in case of multiple GPUs available in your machine) use --gpus '"device=0,1,2..."'
If the command runs successfully, you will get a response similar to the following.
