This repo hosts the checkpoint of RSCoVLM based on Qwen/Qwen2.5-VL-7B-Instruct trained on a comprehensive remote sensing data recipe.

RSCoVLM is a technical practice to fine-tune Large Multimodal language Models for remote sensing image understanding, ultra-high-resolution image reasoning, oriented object detection, and so on. This repo hosts the official model weight of the paper: RSCoVLM: Co-Training Vision Language Models for Remote Sensing Multi-task Learning.

Downloading Guide

You can download with your web browser on the file page.

We recommand downloading in terminal using hf (pip install --upgrade huggingface_hub). You can refer to the document for more usages.

# Set Huggingface Mirror for Chinese users (if required):
export HF_ENDPOINT=https://hf-mirror.com 
# Download a certain checkpoint:
hf download Qingyun/RSCoVLM-7B-2512 --repo-type model --local-dir checkpoint/RSCoVLM-7B-2512/
# If any error (such as network error) interrupts the downloading, you just need to execute the same command, the latest hf will resume downloading.
