YOLOv8 re-implementation using PyTorch

Installation

conda create -n YOLO python=3.8
conda activate YOLO
conda install pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch-lts
pip install opencv-python==4.5.5.64
pip install PyYAML
pip install tqdm

Train

• Configure your dataset path in main.py for training
• Run bash main.sh $ --train for training, $ is number of GPUs

Test

• Configure your dataset path in main.py for testing
• Run python main.py --test for testing

Results

Version	Epochs	Box mAP	Download
v8_n	500	37.0	model
v8_n*	500	37.2	model
v8_s*	500	44.6	model
v8_m*	500	50.0	model
v8_l*	500	52.5	model
v8_x*	500	53.5	model

• * means that weights are ported from original repo, see reference
• In the official YOLOv8 code, mask annotation information is used, which leads to higher performance
