# LayoutLM for Visual Question Answering
|
|
|
|
This is a fine-tuned version of the multi-modal [LayoutLM](https://aka.ms/layoutlm) model for the task of question answering on documents. It has been fine-tuned on

|
|
## Model details
|
|
|
|
The LayoutLM model was developed at Microsoft ([paper](https://arxiv.org/abs/1912.13318)) as a general purpose tool for understanding documents. This model is a fine-tuned checkpoint of [LayoutLM-Base-Cased](https://huggingface.co/microsoft/layoutlm-base-uncased), using both the [SQuAD2.0](https://huggingface.co/datasets/squad_v2) and [DocVQA](https://www.docvqa.org/) datasets.
|
|
|
|
## Getting started with the model
|
|
|
|
To run these examples, you must have [PIL](https://pillow.readthedocs.io/en/stable/installation.html), [pytesseract](https://pypi.org/project/pytesseract/), and [PyTorch](https://pytorch.org/get-started/locally/) installed in addition to [transformers](https://huggingface.co/docs/transformers/index).
|
|
|
|
```python
|
|
from transformers import AutoTokenizer, pipeline
|
|
|
|
tokenizer = AutoTokenizer.from_pretrained(
|
|
"impira/layoutlm-document-qa",
|
|
add_prefix_space=True,
|
|
trust_remote_code=True,
|
|
)
|
|
|
|
nlp = pipeline(
|
|
model="impira/layoutlm-document-qa",
|
|
tokenizer=tokenizer,
|
|
trust_remote_code=True,
|
|
)
|
|
|
|
nlp(
|
|
"https://templates.invoicehome.com/invoice-template-us-neat-750px.png",
|
|
"What is the invoice number?"
|
|
)
|
|
# {'score': 0.9943977, 'answer': 'us-001', 'start': 15, 'end': 15}
|
|
|
|
nlp(
|
|
"https://miro.medium.com/max/787/1*iECQRIiOGTmEFLdWkVIH2g.jpeg",
|
|
"What is the purchase amount?"
|
|
)
|
|
# {'score': 0.9912159, 'answer': '$1,000,000,000', 'start': 97, 'end': 97}
|
|
|
|
nlp(
|
|
"https://www.accountingcoach.com/wp-content/uploads/2013/10/income-statement-example@2x.png",
|
|
"What are the 2020 net sales?"
|
|
)
|
|
# {'score': 0.59147286, 'answer': '$ 3,750', 'start': 19, 'end': 20}
|
|
```
|
|
|
|
**NOTE**: This model relies on a [model definition](https://github.com/huggingface/transformers/pull/18407) and [pipeline](https://github.com/huggingface/transformers/pull/18414) that are currently in review to be included in the transformers project. In the meantime, you'll have to use the `trust_remote_code=True` flag to run this model.
