🦾 Update

[2023-11]: Supporting GPT4V's Evaluation on 8 Benchmarks; Anouncing OtterHD-8B, improved from Fuyu-8B. Checkout OtterHD for details.

1. 🦦 Added OtterHD, a multimodal fine-tuned from Fuyu-8B to facilitate fine-grained interpretations of high-resolution visual input without a explicit vision encoder module. All image patches are linear transformed and processed together with text tokens. This is a very innovative and elegant exploration. We are fascinated and paved in this way, we opensourced the finetune script for Fuyu-8B and improve training throughput by 4-5 times faster with Flash-Attention-2. Try our finetune script at OtterHD.
2. 🔍 Added MagnifierBench, an evaluation benchmark tailored to assess whether the model can identify the tiny objects' information (1% image size) and spatial relationships.
3. Improved pipeline for Pretrain | SFT | RLHF with (part of) current leading LMMs.
   1. Models: Otter | OpenFlamingo | Idefics | Fuyu
   2. Training Datasets Interface: (Pretrain) MMC4 | LAION2B | CC3M | CC12M, (SFT) MIMIC-IT | M3IT | LLAVAR | LRV | SVIT...
      • We tested above datasets for both pretraining and instruction tuning with OpenFlamingo and Otter. We also tested the datasets with Idefics and Fuyu for instruction tuning. We will opensource the training scripts gradually.
   3. Benchmark Interface: MagnifierBench/MMBench/MM-VET/MathVista/POPE/MME/SicenceQA/SeedBench. Run them can be in one-click, please see Benchmark for details.

       datasets:
       - name: magnifierbench
           split: test
           prompt: Answer with the option's letter from the given choices directly.
           api_key: [Your API Key] # GPT4 or GPT3.5 to evaluate the answers and ground truth.
           debug: true # put debug=true will save the model response in log file.
       - name: mme
           split: test
           debug: true
       - name: mmbench
           split: test
           debug: true
   
       models:
       - name: gpt4v
           api_key: [Your API Key] # to call GPT4V model.

   4. Code refactorization for organizing multiple groups of datasets with integrated yaml file, see details at managing datasets in MIMIC-IT format. For example,

       IMAGE_TEXT: # Group name should be in [IMAGE_TEXT, TEXT_ONLY, IMAGE_TEXT_IN_CONTEXT]
           LADD: # Dataset name can be assigned at any name you want
               mimicit_path: azure_storage/json/LA/LADD_instructions.json # Path of the instruction json file
               images_path: azure_storage/Parquets/LA.parquet # Path of the image parquet file
               num_samples: -1 # Number of samples you want to use, -1 means use all samples, if not set, default is -1.
           M3IT_CAPTIONING:
               mimicit_path: azure_storage/json/M3IT/captioning/coco/coco_instructions.json
               images_path: azure_storage/Parquets/coco.parquet
               num_samples: 20000

   This is a major change and would result previous code not runnable, please check the details.

3. 🤗 Check our paper introducing MIMIC-IT in details. Meet MIMIC-IT, the first multimodal in-context instruction tuning dataset with 2.8M instructions! From general scene understanding to spotting subtle differences and enhancing egocentric view comprehension for AR headsets, our MIMIC-IT dataset has it all.

🦦 Why In-Context Instruction Tuning?

Large Language Models (LLMs) have demonstrated exceptional universal aptitude as few/zero-shot learners for numerous tasks, owing to their pre-training on extensive text data. Among these LLMs, GPT-3 stands out as a prominent model with significant capabilities. Additionally, variants of GPT-3, namely InstructGPT and ChatGPT, have proven effective in interpreting natural language instructions to perform complex real-world tasks, thanks to instruction tuning.

Motivated by the upstream interleaved format pretraining of the Flamingo model, we present 🦦 Otter, a multi-modal model based on OpenFlamingo (the open-sourced version of DeepMind's Flamingo). We train our Otter in an in-context instruction tuning way on our proposed MI-Modal In-Context Instruction Tuning (MIMIC-IT) dataset. Otter showcases improved instruction-following and in-context learning ability in both images and videos.

🗄 MIMIC-IT Dataset Details

MIMIC-IT enables the application of egocentric visual assistant model that can serve that can answer your questions like Hey, Do you think I left my keys on the table?. Harness the power of MIMIC-IT to unlock the full potential of your AI-driven visual assistant and elevate your interactive vision-language tasks to new heights.

We also introduce Syphus, an automated pipeline for generating high-quality instruction-response pairs in multiple languages. Building upon the framework proposed by LLaVA, we utilize ChatGPT to generate instruction-response pairs based on visual content. To ensure the quality of the generated instruction-response pairs, our pipeline incorporates system messages, visual annotations, and in-context examples as prompts for ChatGPT.

For more details, please check the MIMIC-IT dataset.

🤖 Otter Model Details

Otter is designed to support multi-modal in-context instruction tuning based on the OpenFlamingo model, which involves conditioning the language model on the corresponding media, such as an image that corresponds to a caption or an instruction-response pair.

We train Otter on MIMIC-IT dataset with approximately 2.8 million in-context instruction-response pairs, which are structured into a cohesive template to facilitate various tasks. Otter supports videos inputs (frames are arranged as original Flamingo's implementation) and multiple images inputs as in-context examples, which is the first multi-modal instruction tuned model.

The following template encompasses images, user instructions, and model-generated responses, utilizing the User and GPT role labels to enable seamless user-assistant interactions.

prompt = f"<image>User: {instruction} GPT:<answer> {response}<endofchunk>"

Training the Otter model on the MIMIC-IT dataset allows it to acquire different capacities, as demonstrated by the LA and SD tasks. Trained on the LA task, the model exhibits exceptional scene comprehension, reasoning abilities, and multi-round conversation capabilities.

# multi-round of conversation
prompt = f"<image>User: {first_instruction} GPT:<answer> {first_response}<endofchunk>User: {second_instruction} GPT:<answer>"

Regarding the concept of organizing visual-language in-context examples, we demonstrate here the acquired ability of the Otter model to follow inter-contextual instructions after training on the LA-T2T task. The organized input data format is as follows:

# Multiple in-context example with similar instructions
prompt = f"<image>User:{ict_first_instruction} GPT: <answer>{ict_first_response}<|endofchunk|><image>User:{ict_second_instruction} GPT: <answer>{ict_second_response}<|endofchunk|><image>User:{query_instruction} GPT: <answer>"

For more details, please refer to our paper's appendix for other tasks.

🗂️ Environments

1. Compare cuda version returned by nvidia-smi and nvcc --version. They need to match. Or at least, the version get by nvcc --version should be <= the version get by nvidia-smi.
2. Install the pytorch that matches your cuda version. (e.g. cuda 11.7 torch 2.0.0). We have successfully run this code on cuda 11.1 torch 1.10.1 and cuda 11.7 torch 2.0.0. You can refer to PyTorch's documentation, Latest or Previous.
3. You may install via conda env create -f environment.yml. Especially to make sure the transformers>=4.28.0, accelerate>=0.18.0.

After configuring environment, you can use the 🦩 Flamingo model / 🦦 Otter model as a 🤗 Hugging Face model with only a few lines! One-click and then model configs/weights are downloaded automatically. Please refer to Huggingface Otter/Flamingo for details.

☄️ Training

Otter is trained based on OpenFlamingo. You may need to use converted weights at luodian/OTTER-9B-INIT or luodian/OTTER-MPT7B-Init. They are respectively converted from OpenFlamingo-LLaMA7B-v1 and OpenFlamingo-MPT7B-v2, we added a <answer> token for Otter's downstream instruction tuning.

You may also use any trained Otter weights to start with your training on top of ours, see them at Otter Weights. You can refer to MIMIC-IT for preparing image/instruction/train json files.
