## Model Summary |
|
|
|
NLLB-SigLIP-MRL is a model that combines a text encoder from the [NLLB model](https://huggingface.co/facebook/nllb-200-distilled-600M) and an image encoder from the |
|
[SigLIP](https://huggingface.co/timm/ViT-B-16-SigLIP-384) model. This allows us to extend the model capabilities |
|
to 201 languages of the Flores-200. This version of the model was trained using a variation of [Matryoshka Representation learning](https://arxiv.org/abs/2205.13147) |
|
to enable the generation of embeddings of sizes [32, 64, 128, 256, 512] in addition to the original 768. Based on the benchmarks below, embeddings of sizes 256 and 512 |
|
preserve 90%+ of the full embedding quality. |
|
|
|
 |
|
|
|
The full embedding model sets new state-of-the-art for multilingual image and text retrieval on both XTD10 and Crossmodal-3600. |

## How to use |
|
|
|
### Variable resolutions |

|
</a> |
|
|
|
If you want to use the model that supports variable embedding sizes, you can do it as follows: |
|
|
|
``` |
|
!pip install -U transformers open_clip_torch |
|
``` |
|
|
|
``` |
|
from transformers import AutoModel |
|
from PIL import Image |
|
import requests |
|
import torch |
|
|
|
model = AutoModel.from_pretrained("visheratin/nllb-siglip-mrl-base", device="cpu", trust_remote_code=True) |
|
|
|
image_path = "https://huggingface.co/spaces/jjourney1125/swin2sr/resolve/main/samples/butterfly.jpg" |
|
image = Image.open(requests.get(image_path, stream=True).raw) |
|
|
|
class_options = ["бабочка", "butterfly", "kat"] |
|
class_langs = ["rus_Cyrl", "eng_Latn", "afr_Latn"] |
|
|
|
image_logits, text_logits = model.get_logits( |
|
images=[image], |
|
texts=class_options, |
|
langs=class_langs, |
|
resolution=512 # set resolution here or set `None` to use the original resolution |
|
) |
|
|
|
print(torch.softmax(image_logits, dim=1)) |
|
``` |
|
|
|
### OpenCLIP |
|
|
|
This model is also integrated into OpenCLIP so that you can use it as any other model: |
|
|
|
``` |
|
!pip install -U open_clip_torch |
|
``` |
|
|
|
``` |
|
from open_clip import create_model_from_pretrained, get_tokenizer |
|
from PIL import Image |
|
import requests |
|
import torch |
|
|
|
model, transform = create_model_from_pretrained("nllb-clip-base-siglip", "mrl", device="cuda") |
|
|
|
tokenizer = get_tokenizer("nllb-clip-base-siglip") |
|
|
|
class_options = ["бабочка", "butterfly", "kat"] |
|
class_langs = ["rus_Cyrl", "eng_Latn", "afr_Latn"] |
|
|
|
text_inputs = [] |
|
for i in range(len(class_options)): |
|
tokenizer.set_language(class_langs[i]) |
|
text_inputs.append(tokenizer(class_options[i])) |
|
text_inputs = torch.stack(text_inputs).squeeze(1).to("cuda") |
|
|
|
image_path = "https://huggingface.co/spaces/jjourney1125/swin2sr/resolve/main/samples/butterfly.jpg" |
|
image = Image.open(requests.get(image_path, stream=True).raw) |
|
|
|
image_inputs = transform(image).unsqueeze(0).to("cuda") |
|
|
|
with torch.inference_mode(): |
|
logits_per_image, logits_per_text = model.get_logits(image_inputs, text_inputs) |
|
|
|
print(logits_per_image.softmax(dim=-1)) |
|
``` |
