en license: cc-by-nc-4.0 library_name: transformers --- ## Introduction We present NV-Embed-v2, a generalist embedding model that ranks No. 1 on the Massive Text Embedding Benchmark ([MTEB benchmark](https://huggingface.co./spaces/mteb/leaderboard))(as of Aug 30, 2024) with a score of 72.31 across 56 text embedding tasks. It also holds the No. 1 in the retrieval sub-category (a score of 62.65 across 15 tasks) in the leaderboard, which is essential to the development of RAG technology. NV-Embed-v2 presents several new designs, including having the LLM attend to latent vectors for better pooled embedding output, and demonstrating a two-staged instruction tuning method to enhance the accuracy of both retrieval and non-retrieval tasks. Additionally, NV-Embed-v2 incorporates a novel hard-negative mining methods that take into account the positive relevance score for better false negatives removal. For more technical details, refer to our paper: [NV-Embed: Improved Techniques for Training LLMs as Generalist Embedding Models](https://arxiv.org/pdf/2405.17428). ## Model Details - Base Decoder-only LLM: [Mistral-7B-v0.1](https://huggingface.co./mistralai/Mistral-7B-v0.1) - Pooling Type: Latent-Attention - Embedding Dimension: 4096 ## How to use Here is an example of how to encode queries and passages using Huggingface-transformer and Sentence-transformer.

So without further ado, let's get to the question. Are Judo throws allowed in wrestling? Yes, judo throws are allowed in freestyle and folkstyle wrestling. You only need to be careful to follow the slam rules when executing judo throws.

Refer the [license](https://spdx.org/licenses/CC-BY-NC-4.0) for the detailed terms. For commercial purpose, we recommend you to use the models of [NeMo Retriever Microservices (NIMs)](https://build.nvidia.com/explore/retrieval). ## Correspondence to Chankyu Lee (chankyul@nvidia.com), Wei Ping (wping@nvidia.com) ## Citation If you find this code useful in your research, please consider citing: ```bibtex @article{lee2024nv, title={NV-Embed: Improved Techniques for Training LLMs as Generalist Embedding Models}, author={Lee, Chankyu and Roy, Rajarshi and Xu, Mengyao and Raiman, Jonathan and Shoeybi, Mohammad and Catanzaro, Bryan and Ping, Wei}, journal={arXiv preprint arXiv:2405.17428}, year={2024} } ``` ```bibtex @article{moreira2024nv, title={NV-Retriever: Improving text embedding models with effective hard-negative mining}, author={Moreira, Gabriel de Souza P and Osmulski, Radek and Xu, Mengyao and Ak, Ronay and Schifferer, Benedikt and Oldridge, Even}, journal={arXiv preprint arXiv:2407.15831}, year={2024} } ``` ## Troubleshooting #### 1. Instruction template for MTEB benchmarks For MTEB sub-tasks for retrieval, STS, summarization, please use the instruction prefix template in [instructions.json](https://huggingface.co./nvidia/NV-Embed-v2/blob/main/instructions.json). For classification, clustering and reranking, please use the instructions provided in Table. 7 in [NV-Embed paper](https://arxiv.org/pdf/2405.17428). #### 2. Required Packages If you have trouble, try installing the python packages as below ```python pip uninstall -y transformer-engine pip install torch==2.2.0 pip install transformers==4.42.4 pip install flash-attn==2.2.0 pip install sentence-transformers==2.7.0 ``` #### 3. How to enable Multi-GPU (Note, this is the case for HuggingFace Transformers) ```python from transformers import AutoModel from torch.nn import DataParallel embedding_model = AutoModel.from_pretrained("nvidia/NV-Embed-v2") for module_key, module in embedding_model._modules.items(): embedding_model._modules[module_key] = DataParallel(module) ``` #### 4. Fixing "nvidia/NV-Embed-v2 is not the path to a directory containing a file named config.json" Switch to your local model path，and open config.json and change the value of **"_name_or_path"** and replace it with your local model path. #### 5. Access to model nvidia/NV-Embed-v2 is restricted. You must be authenticated to access it Use your huggingface access [token](https://huggingface.co./settings/tokens) to execute *"huggingface-cli login"*. #### 6. How to resolve slight mismatch in Sentence transformer results. A slight mismatch in the Sentence Transformer implementation is caused by a discrepancy in the calculation of the instruction prefix length within the Sentence Transformer package. To fix this issue, you need to build the Sentence Transformer package from source, making the necessary modification in this [line](https://github.com/UKPLab/sentence-transformers/blob/v2.7-release/sentence_transformers/SentenceTransformer.py#L353) as below. ```python git clone https://github.com/UKPLab/sentence-transformers.git cd sentence-transformers git checkout v2.7-release # Modify L353 in SentenceTransformer.py to **'extra_features["prompt_length"] = tokenized_prompt["input_ids"].shape[-1]'**. pip install -e . ```
