[ICCV2025] Accelerate 3D Object Detection Models via Zero-Shot Attention Key Pruning
May 9, 2026 · View on GitHub
This is the implentation for our paper "Accelerate 3D Object Detection Models via Zero-Shot Attention Key Pruning"

Introduction
We propose a zero-shot, retraining-free pruning method that accelerates 3D object detection models via key pruning.
News
- [2025/06/26]🔥Our paper is accepted by ICCV 2025 🎉🎉🎉.
- [2025/03/11]🔥We release our code and checkpoints.
Get Started
You need pytorch to use tgGBC.
# 1. install your pytorch.
pip3 install torch torchvision torchaudio
# 2. clone this repo.
git clone https://github.com/iseri27/tg_gbc
cd tg_gbc
# 3. install tggbc
python setup.py develop
Examples
Evaluation
We provide an example of OPEN in examples/open to help you evaluate models with tgGBC.
Training
We provide an example of StreamPETR in examples/streampetr to help you train models with tgGBC. We also provide some checkpoints of StreamPETR-vov-1600x640.
