+# ColQwen2.5-Omni: Visual+Audio Retriever based on Qwen2.5-Omni-3B-Instruct with ColBERT strategy
+ColQwen-Omni is a model based on a novel model architecture and training strategy based on Omnimodal Language Models to efficiently index documents from their visual features.
+It is a Qwen2.5-Omni-3B extension that generates [ColBERT](https://arxiv.org/abs/2004.12832)- style multi-vector representations of text and images.
+It was introduced in the paper [ColPali: Efficient Document Retrieval with Vision Language Models](https://arxiv.org/abs/2407.01449) and first released in [this repository](https://github.com/ManuelFay/colpali)
+<p align="center"><img width=800 src="https://github.com/illuin-tech/colpali/blob/main/assets/colpali_architecture.webp?raw=true"/></p>
+## Version specificity
+This model takes dynamic image resolutions in input and does not resize them, changing their aspect ratio as in ColPali.
+Maximal resolution is set so that 1024 image patches are created at most. Experiments show clear improvements with larger amounts of image patches, at the cost of memory requirements.
+This version is trained with `colpali-engine==0.3.11`.
+Data is the same as the ColPali data described in the paper.
+## Model Training
+### Dataset (Fully Image)
+Our training dataset of 127,460 query-page pairs is comprised of train sets of openly available academic datasets (63%) and a synthetic dataset made up of pages from web-crawled PDF documents and augmented with VLM-generated (Claude-3 Sonnet) pseudo-questions (37%).
+Our training set is fully English by design, enabling us to study zero-shot generalization to non-English languages. We explicitly verify no multi-page PDF document is used both [*ViDoRe*](https://huggingface.co/collections/vidore/vidore-benchmark-667173f98e70a1c0fa4db00d) and in the train set to prevent evaluation contamination.
+A validation set is created with 2% of the samples to tune hyperparameters.
+*Note: Multilingual data is present in the pretraining corpus of the language model and most probably in the multimodal training.*
+## Usage
+Make sure `colpali-engine` is installed from source or with a version superior to 0.3.11.
+```bash
+pip install git+https://github.com/illuin-tech/colpali
+```
+```python
+import torch
+from PIL import Image
+from transformers.utils.import_utils import is_flash_attn_2_available
+from tqdm import tqdm
+from torch.utils.data import DataLoader
+from colpali_engine.models import ColQwen2_5Omni, ColQwen2_5OmniProcessor

+    device_map="cuda",  # or "mps" if on Apple Silicon

+).eval()
+processor = ColQwen2_5OmniProcessor.from_pretrained("vidore/colqwen-omni-v0.1")
+dataset = load_dataset("eustlb/dailytalk-conversations-grouped", split="train[:500]")
+audios = [x["array"] for x in dataset["audio"]]

+ds  = []
+for batch_doc in tqdm(dataloader):
+    with torch.no_grad():
+        batch_doc = {k: v.to(model.device) for k, v in batch_doc.items()}
+        embeddings_doc = model(**batch_doc)
+    ds.extend(list(torch.unbind(embeddings_doc.to("cpu"))))
+def get_results(query: str, k=10):
+    batch_queries = processor.process_queries([query]).to(model.device)
+    # Forward pass
+    with torch.no_grad():
+        query_embeddings = model(**batch_queries)
+    scores = processor.score_multi_vector(query_embeddings, ds)
+    # get top-5 scores
+    return scores[0].topk(k).indices.tolist()
+res = get_results("C'est une chaine TV de quoi ?")
+# In colab
+display(Audio(dataset[res[0]]["audio"]["array"], autoplay=True, rate=dataset[res[0]]["audio"]["sampling_rate"]))
