Install and Use

This page describes how to deploy and configure Document Understanding, as well as special instructions on how to use Document Understanding on Automation Suite.

Dependencies

Document Understanding has a dependency on AI Center, meaning that AI Center always needs to be installed if Document Understanding is installed.

Also, Orchestrator must be activated before using Document Understanding.

Hardware Requirements

Before starting the Document Understanding installation, make sure to check and satisfy all requirements for Automation Suite for single-node here and for multi-node here.

A GPU is strongly recommended for Document Understanding in one of the following scenarios:

If you retrain the Document Understanding models (DocumentUnderstanding - the general model, Invoices,Receipts, etc.) on AI Center.
Training on CPU is 5-7 times slower and model performance degrades compared to training on GPU.
If you run UiPathDocumentOCR (non-edge version) on AI Center to process more than 2 million pages a year.
If you do not use a GPU, slow performance may impact the product experience.

For more details about how to provision a GPU, see Adding a dedicated agent node with GPU support.

SQL Server Requirements

Document Understanding requires the FullTextSearch feature to be enabled on the SQL server. Otherwise, the installation fails without an explicit error message.

Online Installation

For more information on installing Document Understanding in an online environment, see the following guides:

The process is mostly the same as installing other services, and the only requirement is to ensure that AI Center and Document Understanding are enabled.

If you are using the interactive installer, please make sure to select both products following the steps.
If you are not using the interactive installer, please set AI Center and Document Understanding enabled in the config file before installation, or in ArgoCD after installation.

Sample configuration file is included in the Document Understanding configuration file page.

Offline Installation

For more information on installing Document Understanding in an offline environment, see the following guides:

The changes below are required for a successful installation of Document Understanding in an offline environment:

Make sure that AI Center and Document Understanding are set to enabled in the config file before installation, or in ArgoCD after installation. Please make sure handwriting is enabled as well in the config file if you want to use the feature.
Sample configuration file is included in the Document Understanding configuration file page.
Make sure that the Document Understanding bundle is downloaded and installed.
