NVIDIA-Ingest is a scalable, performance-oriented document content and metadata extraction microservice. Including support for parsing PDFs, Word and PowerPoint documents, it uses specialized NVIDIA NIM microservices to find, contextualize, and extract text, tables, charts and images for use in downstream generative applications.
NVIDIA Ingest enables parallelization of the process of splitting documents into pages where contents are classified (as tables, charts, images, text), extracted into discrete content, and further contextualized via optical character recognition (OCR) into a well defined JSON schema. From there, NVIDIA Ingest can optionally manage computation of embeddings for the extracted content, and also optionally manage storing into a vector database Milvus.
A microservice that:
- Accepts a JSON Job description, containing a document payload, and a set of ingestion tasks to perform on that payload.
- Allows the results of a Job to be retrieved; the result is a JSON dictionary containing a list of Metadata describing objects extracted from the base document, as well as processing annotations and timing/trace data.
- Supports PDF, Docx, pptx, and images.
- Supports multiple methods of extraction for each document type in order to balance trade-offs between throughput and accuracy. For example, for PDF documents we support extraction via pdfium, Unstructured.io, and Adobe Content Extraction Services.
- Supports various types of pre and post processing operations, including text splitting and chunking; transform, and filtering; embedding generation, and image offloading to storage.
A service that:
- Runs a static pipeline or fixed set of operations on every submitted document.
- Acts as a wrapper for any specific document parsing library.

- Linux operating systems (Ubuntu 22.04 or later recommended)
- Docker
- Docker Compose
- CUDA Toolkit (NVIDIA Driver >=
535, CUDA >=12.2) - NVIDIA Container Toolkit
To get started using NVIDIA Ingest, you need to do a few things:
- Start supporting NIM microservices 🏗️
- Install the NVIDIA Ingest client dependencies in a Python environment 🐍
- Submit ingestion job(s) 📓
- Inspect and consume results 🔍
Optional:
This example demonstrates how to use the provided docker-compose.yaml to start all needed services with a few commands.
Important
NIM containers on their first startup can take 10-15 minutes to pull and fully load models.
If preferred, you can also start services one by one, or run on Kubernetes via our Helm chart. Also of note are additional environment variables you may wish to configure.
-
Git clone the repo:
git clone https://github.com/nvidia/nv-ingest -
Change directory to the cloned repo
cd nv-ingest. -
Generate API keys and authenticate with NGC with the
docker logincommand:
# This is required to access pre-built containers and NIM microservices
$ docker login nvcr.io
Username: $oauthtoken
Password: <Your Key>Note
during the early access (EA) phase, your API key must be created as a member of nemo-microservice / ea-participants which you may join by applying for early access here: https://developer.nvidia.com/nemo-microservices-early-access/join. When approved, switch your profile to this org / team, then the key you generate will have access to the resources outlined below.
- Create a .env file containing your NGC API key, and the following paths:
# Container images must access resources from NGC.
NGC_API_KEY=... # Optional, set this if you are deploying NIMs locally from NGC
NVIDIA_BUILD_API_KEY=... # Optional, set this is you are using build.nvidia.com NIMs
Note
As configured by default in docker-compose.yaml, the DePlot NIM is on a dedicated GPU. All other NIMs and the nv-ingest container itself share a second. This is to avoid DePlot and other NIMs competing for VRAM on the same device.
Change the CUDA_VISIBLE_DEVICES pinnings as desired for your system within docker-compose.yaml.
Important
Make sure NVIDIA is set as your default container runtime before running the docker compose command with the command:
sudo nvidia-ctk runtime configure --runtime=docker --set-as-default
- Start all services:
docker compose up
Tip
By default we have configured log levels to be verbose.
It's possible to observe service startup proceeding: you will notice many log messages. Disable verbose logging by configuring NIM_TRITON_LOG_VERBOSE=0 for each NIM in docker-compose.yaml.
If you want to build from source, use docker compose up --build instead. This will build from your repo's code rather than from an already published container.
- When all services have fully started,
nvidia-smishould show processes like the following:
# If it's taking > 1m for `nvidia-smi` to return, it's likely the bus is still busy setting up the models.

Tip
nv-ingest is in Early Access mode, meaning the codebase gets frequent updates. To build an updated nv-ingest service container with the latest changes you can:
docker compose build
After the image is built, run docker compose up per item 5 above.
To interact with the nv-ingest service, you can do so from the host, or by docker exec-ing into the nv-ingest container.
To interact from the host, you'll need a Python environment and install the client dependencies:
# conda not required, but makes it easy to create a fresh python environment
conda create --name nv-ingest-dev --file ./conda/environments/nv_ingest_environment.yml
conda activate nv-ingest-dev
cd client
pip install .
# When not using Conda, pip dependencies for the client can be installed directly via pip. Pip based installation of
# the ingest service is not supported.
cd client
pip install -r requirements.txt
pip install .Note
Interacting from the host depends on the appropriate port being exposed from the nv-ingest container to the host as defined in docker-compose.yaml.
If you prefer, you can disable exposing that port, and interact with the nv-ingest service directly from within its container.
To interact within the container:
docker exec -it nv-ingest-nv-ingest-ms-runtime-1 bash
You'll be in the /workspace directory, which has DATASET_ROOT from the .env file mounted at ./data. The pre-activated morpheus conda environment has all the python client libraries pre-installed:
(morpheus) root@aba77e2a4bde:/workspace#
From the bash prompt above, you can run nv-ingest-cli and Python examples described below.
You can submit jobs programmatically in Python or via the nv-ingest-cli tool.
In the below examples, we are doing text, chart, table, and image extraction:
extract_text, - uses PDFium to find and extract text from pagesextract_images- uses PDFium to extract imagesextract_tables- uses YOLOX to find tables and charts. Uses PaddleOCR for table extraction, and Deplot and CACHED for chart extractionextract_charts- (optional) enables or disables the use of Deplot and CACHED for chart extraction.
Important
extract_tables controls extraction for both tables and charts. You can optionally disable chart extraction by setting extract_charts to false.

After the ingestion steps above have completed, you should be able to find text and image subfolders inside your processed docs folder. Each will contain JSON formatted extracted content and metadata.
ls -R processed_docs/processed_docs/:
image structured text
processed_docs/image:
multimodal_test.pdf.metadata.json
processed_docs/structured:
multimodal_test.pdf.metadata.json
processed_docs/text:
multimodal_test.pdf.metadata.jsonYou can view the full JSON extracts and the metadata definitions here.
We also provide a script for inspecting extracted images
First, install tkinter by running the following commands depending on your OS.
- For Ubuntu/Debian Linux:
sudo apt-get update
sudo apt-get install python3-tk- For Fedora/RHEL Linux:
sudo dnf install python3-tkinter- For macOS using Homebrew:
brew install python-tkThen run the following command to execute the script for inspecting the extracted image:
python src/util/image_viewer.py --file_path ./processed_docs/image/multimodal_test.pdf.metadata.jsonTip
Beyond inspecting the results, you can read them into things like llama-index or langchain retrieval pipelines.
Please also checkout our demo using a retrieval pipeline on build.nvidia.com to query over document content pre-extracted w/ NVIDIA Ingest.
