HPS Pretrained Model Training Demo
Overview
This notebook demonstrates how to use HPS to load pre-trained embedding tables. It is recommended to run hierarchical_parameter_server_demo.ipynb before diving into this notebook.
For more details about HPS APIs, please refer to HPS APIs. For more details about HPS, please refer to HugeCTR Hierarchical Parameter Server (HPS).
Installation
Get HPS from NGC
The HPS Python module is preinstalled in the 22.12 and later Merlin TensorFlow Container: nvcr.io/nvidia/merlin/merlin-tensorflow:22.12.
You can check the existence of the required libraries by running the following Python code after launching this container.
$ python3 -c "import hierarchical_parameter_server as hps"
Configurations
First of all we specify the required configurations, e.g., the arguments needed for generating the dataset, the model parameters and the paths to save the model. We will use a deep neural network (DNN) model which has one embedding table and several dense layers. Please note that the input to the embedding layer will be a sparse key tensor.

Train with native TF layers
We define the model graph for training with native TF layers, i.e., tf.nn.embedding_lookup_sparse and tf.keras.layers.Dense. Besides, the embedding weights are stored in tf.Variable. We can then train the model and extract the trained weights of the embedding table.

Load the pre-trained embeddings via HPS
In order to use HPS to load the pre-trained embeddings, they should be converted to the formats required by HPS. After that, we can train a new model which leverages the pre-trained embeddings and only updates the weights of dense layers. Please note that hps.SparseLookupLayer and hps.LookupLayer are not trainable.
In order to initialize the lookup service provided by HPS, we also need to create a JSON configuration file and specify the details of the embedding tables for the models to be deployed. We deploy a model that has one embedding table here, and it can support multiple models with multiple embedding tables actually. Please note how maxnum_catfeature_query_per_table_per_sample is specified for the embedding table: the max_nnz is 5 for all the slots and there are 10 slots, so this entry is configured as 50.
