• MobileVLM V2: Faster and Stronger Baseline for Vision Language Model
  

  Take a quick look at our MobileVLM V2 architecture
  We introduce MobileVLM V2, a family of significantly improved vision language models upon MobileVLM, which proves that a delicate orchestration of novel architectural design, an improved training scheme tailored for mobile VLMs, and rich high-quality dataset curation can substantially benefit VLMs’ performance. Specifically, MobileVLM V2 1.7B achieves better or on-par performance on standard VLM benchmarks compared with much larger VLMs at the 3B scale. Notably, our 3B model outperforms a large variety of VLMs at the 7B+ scale.

  Take a quick look at our MobileVLM architecture
  We present MobileVLM, a competent multimodal vision language model (MMVLM) targeted to run on mobile devices. It is an amalgamation of a myriad of architectural designs and techniques that are mobile-oriented, which comprises a set of language models at the scale of 1.4B and 2.7B parameters, trained from scratch, a multimodal vision model that is pre-trained in the CLIP fashion, cross-modality interaction via an efficient projector. We evaluate MobileVLM on several typical VLM benchmarks. Our models demonstrate on par performance compared with a few much larger models. More importantly, we measure the inference speed on both a Qualcomm Snapdragon 888 CPU and an NVIDIA Jeston Orin GPU, and we obtain state-of-the-art performance of 21.5 tokens and 65.3 tokens per second, respectively.
  

  The MobileVLM architecture (right) utilizes MobileLLaMA as its language model, intakes Xv and Xq which are image and language instructions as respective inputs and gives Ya as the output language response. LDP refers to a lightweight downsample projector.

Example for MobileLLaMA model inference

import torch
from transformers import LlamaTokenizer, LlamaForCausalLM

model_path = 'mtgv/MobileLLaMA-1.4B-Chat'

tokenizer = LlamaTokenizer.from_pretrained(model_path)
model = LlamaForCausalLM.from_pretrained(
    model_path, torch_dtype=torch.float16, device_map='auto',
)

prompt = 'Q: What is the largest animal?\nA:'
input_ids = tokenizer(prompt, return_tensors="pt").input_ids

generation_output = model.generate(
    input_ids=input_ids, max_new_tokens=32
)
print(tokenizer.decode(generation_output[0]))

Step-by-step Tutorial

MobileVLM

The training process of MobileVLM V2 is divided into two stages:

• stage I: pre-training
  • ❄️ frozen vision encoder + learnable LDP V2 projector + learnable LLM
  • this training process takes around 3~5 hours for MobileVLM V2-1.7B/3B on 8x A100 (80G) with a batch size of 256 and an average of approximately 38G/51G of GPU memory required.
• stage II: multi-task training
  • ❄️ frozen vision encoder + learnable LDP V2 projector + learnable LLM
  • this training process takes around 9~12 hours for MobileVLM V2-1.7B/3B on 8x A100 (80G) with a batch size of 128 and an average of approximately 45G/52G of GPU memory required.
• note: if you are interest in MobileVLM V1 training recipe, please refer to our previous README.

1️⃣ Prepare MobileLLaMA checkpoints

Similar to MobileVLM, please firstly download MobileLLaMA chatbot checkpoints from huggingface website ( 1.7B, 2.7B). Please note that this is optional (it depends on your working environment), run the training script we provide below and the model will be automatically downloaded by the transformers library.

2️⃣ Prepare data

• For convenience, assume your working directory /path/to/project/mobilevlm as work_dir:

  • cd ${work_dir} && mkdir -p data/pretrain_data data/finetune_data data/benchmark_data

• prepare pre-training data

  • cd ${work_dir}/data/pretrain_data
  • download the ShareGPT4V-PT from here, which is provided by ShareGPT4V team.

• prepare multi-task training data

  • cd ${work_dir}/data/finetune_data
  • download the annotation of our MobileVLM_V2_FT_Mix2M data from huggingface here, and download the images from constituting datasets: Text-VQA, IConQA, SQA, SBU, follow ShareGPT4V to download images from: LAION-CC-SBU-558K, COCO, WebData, SAM, GQA, OCR-VQA, TextVQA, VisualGnome (Part1, Part2)

• prepare benchmark data

  • We evaluate models on a diverse set of 6 benchmarks, i.e. GQA, MMBench, MME, POPE, SQA, TextVQA. We do not evaluate using beam search to make the inference process consistent with the chat demo of real-time outputs. You should follow these instructions to manage the datasets.
