Merlin NVTabular Core Features
Feature Engineering
NVTabular's fast feature transforms reduce data prep time and eases deploying recommender models to production. With NVTabular recommender focused APIs, data scientists and machine learning engineers are able to quickly process datasets of all sizes, implement more experimentation, and are not bound by CPU or GPU memory. Also, includes multi-hot categoricals and vector continuous passing support to ease feature engineering.
Run examples
Interoperability with Open Source
Data scientists and machine learning engineers use a hybrid of methods, tools, libraries, and frameworks, including open source. NVTabular native tabular data support includes comma-separated values (CSV) files, Apache Parquet, Apache Orc, and Apache Avro. Also, NVTabular data loaders are optimized for TensorFlow (TF), PyTorch, and Merlin HugeCTR. All Merlin components, including NVTabluar, are interoperable with open source.

Get Started with Merlin NVTabular
All NVIDIA Merlin components are available as open-source projects on GitHub. However, a more convenient way to make use of these components is by using Merlin NVTabular containers from the NVIDIA NGC catalog. Containers package the software application, libraries, dependencies, and runtime compilers in a self-contained environment. This way, the application environment is both portable, consistent, reproducible, and agnostic to the underlying host system software configuration.
