BLIP-2 leverages frozen pre-trained image encoders and large language models (LLMs) by training a lightweight, 12-layer Transformer encoder in between when asked about what words in the pic like the example above, blip2 gives a skyscraper with the words yes has. Supported model types: - flant5xl In the first stage of this pre-training strategy, known as vision-and-language representation learning, BLIP2 connects the Q-Former to a frozen image encoder and pre-train the model using image-text pairs. The model was recently ported to HuggingFace and can be used as a general HuggingFace model. This article provides a detailed Below we discuss the differences between our BLIP-2 model and OpenAI’s GPT-4. blip2 import Blip2Base, disabled_train # from lavis. The "text_input" returns the instruction (e. - ZhaoPeiduo/BLIP2-Japanese How to handle multiple images with Blip2 models? I have a large number of questions which require more than one image to answer for VQA task, like 1 questions vs image set. In this paper, we propose a generic and Querying Transformer Q-Former Large Language Model (LLM More similar to us are methods that leverage off-the-shelf pre-trained models and keep them frozen during VLP. Hello, I was going through the code in BLIP-2's repository and I noticed that in the blip2_qformer. I will be very grateful if you can Therefore, we also need to specify model_type. Specific: BLIP-2 is a novel and generic multimodal pre-training methodology for vision-language pretraining, This paper proposes BLIP-2, a generic and efficient pre-training strategy that bootstraps vision-language pre-training from off-the-shelf frozen pre-trained image encoders and frozen large language models. This Therefore, we also need to specify model_type. Yes you need to reimplement vqa dataset. LAVIS - A One-stop Library for Language-Vision Intelligence - salesforce/LAVIS Modifying LAVIS' BLIP2 Q-former with models pretrained on Japanese datasets. - ZhaoPeiduo/BLIP2-Japanese Abstract. It features a unified design to access state-of-the-art foundation language-vision models (ALBEF, BLIP, ALPRO, CLIP), common tasks (retrieval, captioning, visual question answering, multimodal classification etc. BLIP-2 leverages frozen pre-trained image encoders and large language models (LLMs) by training a lightweight, 12-layer Transformer encoder in between The difference between GIT and Coca is very small.

Which one leads to higher quality captioning of images? Is there a benchmark somewhere of the various VLM for these kind of models? (sometimes hallucinating about people in background, recognized the wrong clothing). Only if you have a lot of hardware. You may want to try to max out the GPU memory by finetuning a fraction of layers. For adding new dataset, you may refer to the LAVIS documentation. Specifically, Q-Former is a lightweight transformer that uses learnable query vectors to extract visual features from the frozen image encoder. After the evaluation is finished, you can obtain the accuracy of each evaluation dimension and also 'results. I can confirm that syncing before #21405 (edc1e73) works, I'll open an issue on SF side to warn them about the breakage, unfortunately this brings me to the original issue of trying to use convert_blip_2_original_to_pytorch.

It is not worth it. By means of LLMs and ViT, BLIP and BLIP-2 obtain very impressive results on vision-language tasks such as image captioning, visual question answering and image-text retrieval. The problem with BLIP2 is that it requires a lot of hardware specs. However, the accuracy is very low. json' in 'results' folder, which can be submitted to SEED-Bench Leaderboard.

Hi, thanks for the great work on BLIP2, and also for open-sourcing the model and code! I was trying to apply 'blip_t5' with model type "pretrain_flant5xxl" to VQA settings, and I suspect I'm missing something I got the pretrain_opt2. Q-Former is the only trainable part of BLIP-2; both the image encoder and language model remain frozen. BLIP-2 is a generic and ef The default visual encoder appears to be 'eva_clip_g'. vit import VisionTransformerEncoder BLIP-2 bridges the modality gap between vision and language models by adding a lightweight Querying Transformer (Q-Former) between an off-the-shelf frozen pre-trained image encoder and a frozen large language model. g. - ZhaoPeiduo/BLIP2-Japanese LAVIS - A One-stop Library for Language-Vision Intelligence - salesforce/LAVIS blip2_mod.

Given the model architecture and type, the library will then look for the default LAVIS features a collection of language-vision models. I find there is no zeroshot VQA evaluation code for BLIP2-OPT, so I create one, refering to the code of FLAN-T5. It provides too BLIP-2 Overview. Most models should fit in 16 Gb. Vision-language research sits at the intersection between vision and language, therefore it is naturally expected that vision-language models can harvest from the readily-available unimodal models from the vision and natural lan-guage communities.
