unstructured-inference 0.2.0

A library for performing inference using trained models.

Open-Source Pre-Processing Tools for Unstructured Data

The unstructured-inference repo contains hosted model inference code for layout parsing models. These models are invoked via API as part of the partitioning bricks in the unstructured package.

Installation

Package

Requires torch>=1.8. Once this is satisfied, run pip install unstructured-inference.

Repository

Clone the repo and run make install to install dependencies. Run make help for a full list of install options.

Getting Started

To get started with the layout parsing model, use the following commands:

from unstructured_inference.inference.layout import DocumentLayout

layout = DocumentLayout.from_file("sample-docs/loremipsum.pdf")

print(layout.pages[0].elements)

Once the model has detected the layout and OCR'd the document, the text extracted from the first page of the sample document will be displayed. You can convert a given element to a dict by running the .to_dict() method.

To build the Docker container, run make docker-build. Note that Apple hardware with an M1 chip has trouble building Detectron2 on Docker and for best results you should build it on Linux. To run the API locally, use make start-app-local. You can stop the API with make stop-app-local. The API will run at http:/localhost:5000. You can then POST a PDF file to the API endpoint to see its layout with the command:

curl -X 'POST' 'http://localhost:5000/layout/pdf' -F 'file=@<your_pdf_file>' | jq -C . | less -R

You can also choose the types of elements you want to return from the output of PDF parsing by passing a list of types to the include_elems parameter. For example, if you only want to return Text elements and Title elements, you can curl:

curl -X 'POST' 'http://localhost:5000/layout/pdf' \
-F 'file=@<your_pdf_file>' \
-F include_elems=Text \
-F include_elems=Title \
 | jq -C | less -R

If you are using an Apple M1 chip, use make run-app-dev instead of make start-app-local to start the API with hot reloading. The API will run at http:/localhost:8000.
