# Model Card: VinVL for Captioning 🖼️

[Microsoft's VinVL](https://github.com/microsoft/Oscar) base fine-tuned on [HL dataset](https://arxiv.org/abs/2302.12189?context=cs.CL)  for **rationale description generation** downstream task.

# Model fine-tuning 🏋️‍

The model has been finetuned for 10 epochs on the rationale captions of the [HL dataset](https://arxiv.org/abs/2302.12189?context=cs.CL) (available on 🤗 HUB: [michelecafagna26/hl](https://huggingface.co/datasets/michelecafagna26/hl))

# Test set metrics 📈

# Feature extraction ⛏️

This model has a separate Visualbackbone used to extract features.

# Quick start: 🚀

```python
from transformers.pytorch_transformers import BertConfig, BertTokenizer
from oscar.modeling.modeling_bert import BertForImageCaptioning
from oscar.wrappers import OscarTensorizer

ckpt = "path/to/the/checkpoint"
device = "cuda" if torch.cuda.is_available() else "cpu"

# original code
config = BertConfig.from_pretrained(ckpt)
tokenizer = BertTokenizer.from_pretrained(ckpt)
model = BertForImageCaptioning.from_pretrained(ckpt, config=config).to(device)

# This takes care of the preprocessing
tensorizer = OscarTensorizer(tokenizer=tokenizer, device=device)

# numpy-arrays with shape (1, num_boxes, feat_size)
# feat_size is 2054 by default in VinVL
visual_features = torch.from_numpy(feat_obj).to(device).unsqueeze(0)

# labels are usually extracted by the features extractor
labels = [['boat', 'boat', 'boat', 'bottom', 'bush', 'coat', 'deck', 'deck', 'deck', 'dock', 'hair', 'jacket']]

inputs = tensorizer.encode(visual_features, labels=labels)
outputs = model(**inputs)

pred = tensorizer.decode(outputs)

# the output looks like this:
# pred = {0: [{'caption': 'he is on leisure', 'conf': 0.7070220112800598]}
```
