Merlin Models Example Notebooks

The example notebooks demonstrate how to use Merlin Models with TensorFlow on a variety of datasets.

Inventory

Getting Started: Develop a Model for MovieLens: Get started with Merlin Models by training Facebook’s DLRM architecture with only 3 commands.
From ETL to Training RecSys models - NVTabular and Merlin Models integrated example: Learn how the Schema object connects the feature engineering and training steps. You’ll learn how to apply Merlin Models to your own dataset structures.
Iterating over Deep Learning Models: Explore different ranking model architectures, such as Neural Collaborative Filtering (NCF), MLP, DRLM, and Deep & Cross Network (DCN).

Running the Example Notebooks

You can run the examples with Docker containers. Docker containers are available from the NVIDIA GPU Cloud. Access the catalog of containers at http://ngc.nvidia.com/catalog/containers.

Depending on which example you want to run, you should use any one of these Docker containers:

Merlin-Tensorflow-Training (contains Merlin Core, Merlin Models, NVTabular and TensorFlow)
Merlin-Inference (contains Merlin Core, Merlin Models, Merlin Systems, NVTabular, TensorFlow and Triton Inference Server)

Alternatively, you can install Merlin Models from source and other required libraries to run the notebooks on your host.

To run the example notebooks using Docker containers, perform the following steps:

Pull and start the container by running the following command:
```
docker run --gpus all --rm -it \
  -p 8888:8888 -p 8797:8787 -p 8796:8786 --ipc=host \
  <docker container> /bin/bash
```
The container opens a shell when the run command execution is completed. Your shell prompt should look similar to the following example:
```
root@2efa5b50b909:
```
Install JupyterLab with pip by running the following command:
```
pip install jupyterlab
```
For more information, see the JupyterLab Installation Guide.

Start the JupyterLab server by running the following command:

jupyter-lab --allow-root --ip='0.0.0.0'

View the messages in your terminal to identify the URL for JupyterLab. The messages in your terminal show similar lines to the following example:

Or copy and paste one of these URLs:
   http://2efa5b50b909:8888/lab?token=9b537d1fda9e4e9cadc673ba2a472e247deee69a6229ff8d
or http://127.0.0.1:8888/lab?token=9b537d1fda9e4e9cadc673ba2a472e247deee69a6229ff8d

Open a browser and use the 127.0.0.1 URL provided in the messages by JupyterLab.
After you log in to JupyterLab, navigate to the /merlin/examples directory to try out the example notebooks.
