Implementation of "Data-efficient Large Vision Models through Sequential Autoregression".

<p align="center"> <img src="figs/DeLVM.PNG" > </p> <p align="center"> </p> Training general-purpose vision models on purely sequential visual data, eschewing linguistic inputs, has heralded a new frontier in visual understanding. These models are intended to not only comprehend but also seamlessly transit to out-of-domain tasks. However, current endeavors are hamstrung by an over-reliance on colossal models, exemplified by models with upwards of 3B parameters, and the necessity for an extensive corpus of visual data, often comprising a staggering 400B tokens. In this paper, we delve into the development of an efficient, autoregression-based vision model, innovatively architected to operate on a limited dataset. We meticulously demonstrate how this model achieves proficiency in a spectrum of visual tasks spanning both high-level and low-level semantic understanding during the testing phase. Our empirical evaluations underscore the model's agility in adapting to various tasks, heralding a significant reduction in the parameter footprint, and a marked decrease in training data requirements, thereby paving the way for more sustainable and accessible advancements in the field of generalist vision models.

Set up

based on InternLM-v0.2.1dev20231121

Install: https://github.com/InternLM/InternLM/blob/v0.2.1dev20231121/doc/en/install.md

Put your training data to /path/to/data/vision.

Training command: torchrun --nproc_per_node 8 train.py --config ./configs/pretrain_300m.py --launcher torch

Training via KD command: torchrun --nproc_per_node 8 train.py --config ./configs/kd_1b_to_300m.py --launcher torch

Convert model and inference example: ./tools

The corresponding huggingface ckpt can be downloaded at LLaMA-1b-hf Onedrive / LLaMA-1b-hf Baidu Disk and LLaMA-300m-hf.
