HPS Plugin for TensorRT Notebooks

This directory contains a set of Jupyter notebooks that demonstrate how to use the HPS plugin for TensorRT.


The simplest way to run a one of our notebooks is with a Docker container. A container provides a self-contained, isolated, and reproducible environment for repetitive experiments. Docker images are available from the NVIDIA GPU Cloud (NGC). If you prefer to build the HugeCTR Docker image on your own, refer to Set Up the Development Environment With Merlin Containers.

Pull the Container from NGC

Pull a container based on the modeling framework and notebook that you want to run.

To run the demo_for_tf_trained_model.ipynb notebook, pull the Merlin TensorFlow container:

docker pull nvcr.io/nvidia/merlin/merlin-tensorflow:23.02

To run the demo_for_pytorch_trained_model.ipynb notebook, pull the Merlin PyTorch container:

docker pull nvcr.io/nvidia/merlin/merlin-pytorch:23.02

To run the demo_for_hugectr_trained_model.ipynb notebook, pull the Merlin HugeCTR container:

docker pull nvcr.io/nvidia/merlin/merlin-hugectr:23.02

The HPS TensorRT plugin is installed in all the containers.

Clone the HugeCTR Repository

Use the following command to clone the HugeCTR repository:

git clone https://github.com/NVIDIA-Merlin/HugeCTR

Start the Jupyter Notebook

  1. Launch the container in interactive mode (mount the HugeCTR root directory into the container for your convenience) by running the following command.

    docker run --runtime=nvidia --rm -it --cap-add SYS_NICE -u $(id -u):$(id -g) -v $(pwd):/hugectr -w /hugectr -p 8888:8888 nvcr.io/nvidia/merlin/<container-name>:23.02
  2. Start Jupyter using these commands:

    cd /hugectr/hps_trt/notebooks
    jupyter-notebook --allow-root --ip --port 8888 --NotebookApp.token='hugectr'
  3. Connect to your host machine using the 8888 port by accessing its IP address or name from your web browser: http://[host machine]:8888

    Use the token available from the output by running the command above to log in. For example:

    http://[host machine]:8888/?token=aae96ae9387cd28151868fee318c3b3581a2d794f3b25c6b

Notebook List

Here’s a list of notebooks that you can run:

  • benchmark_tf_trained_large_model.ipynb: Provides the steps to benchmark the inference performance of the large model. The model is comprised of one 147GB embedding table and three fully connected layers, for which a TensorRT engine is built with the HPS plugin. Here are the performance metrics at batch size 4096 on different platforms:
