**How to use:** |
|
```python |
|
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"] |
|

|
|
|

|

|
|
|

|

|

|

|
elif i == tokenizer.sep_token_id: |
|
bbox.append([1000] * 4) |
|
else: |
|

|
encoding["bbox"] = torch.tensor([bbox]) |
|
|
|
word_ids = encoding.word_ids(0) |
|

|
|
|

|
