This model trained on DocVQA Dataset on sample of 15000 questions
Code for Training and Prediction (v1): https://www.kaggle.com/tusharcode/training-layoutlm-docvqa
How to use:
from transformers import AutoTokenizer, AutoModelForDocumentQuestionAnswering
from datasets import load_dataset
model_checkpoint = "TusharGoel/LayoutLM-Finetuned-DocVQA"
tokenizer = AutoTokenizer.from_pretrained(model_checkpoint, add_prefix_space=True)
model_predict = AutoModelForDocumentQuestionAnswering.from_pretrained(model_checkpoint)
model_predict.eval()
dataset = load_dataset("nielsr/funsd", split="train")
example = dataset[0]
question = "What's Licensee Number?"
words = example["words"]
boxes = example["bboxes"]
encoding = tokenizer(question.split(), words,
is_split_into_words=True, return_token_type_ids=True, return_tensors="pt")
bbox = []
for i, s, w in zip(encoding.input_ids[0], encoding.sequence_ids(0), encoding.word_ids(0)):
if s == 1:
bbox.append(boxes[w])
elif i == tokenizer.sep_token_id:
bbox.append([1000] * 4)
else:
bbox.append([0] * 4)
encoding["bbox"] = torch.tensor([bbox])
word_ids = encoding.word_ids(0)
outputs = model_predict(**encoding)
loss = outputs.loss
start_scores = outputs.start_logits
end_scores = outputs.end_logits
start, end = word_ids[start_scores.argmax(-1).item()], word_ids[end_scores.argmax(-1).item()]
print(" ".join(words[start : end + 1]))
