Specific: BLIP-2 is a novel and generic multimodal pre-training methodology for vision-language pretraining, which can enable any family of LLMs to understand images and unlock zero-shot image-to-text generation capabilities. Mar 17, 2023 · BLIP-2 vs. Sep 25, 2023 · 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. LAVIS - A One-stop Library for Language-Vision Intelligence - salesforce/LAVIS LAVIS - A One-stop Library for Language-Vision Intelligence - salesforce/LAVIS BLIP2 is fine-tuned on image-text datasets (e. It's fast and more accurate than llava, can recognize text better. com Feb 5, 2023 · Luckily we've added support for the 8-bit algorithm for BLIP-2, meaning that you can load any BLIP-2 checkpoint in 8 bits instead of the default float32. Are there any details you mentioned I need to take care of if I want to fine-tune BLIP2? Thank you! from lavis. g. Yes you need to reimplement vqa dataset. clip_vit import create_clip_vit_L BLIP2 is fine-tuned on image-text datasets (e. It's also able to output bounding boxes. Reload to refresh your session. After the evaluation is finished, you can obtain the accuracy of each evaluation dimension and also 'results.
