YOLOX:

• For training, we train YOLOX series with 300 epochs on COCO.
• For data augmentation, we use the large scale jitter (LSJ), Mosaic augmentation and Mixup augmentation.
• For optimizer, we use SGD with weight decay 0.0005 and base per image lr 0.01 / 64,.
• For learning rate scheduler, we use Cosine decay scheduler.

On the other hand, we are trying to use AdamW to train our reproduced YOLOX. We will update the new results as soon as possible.

Train YOLOX

Single GPU

Taking training YOLOX-S on COCO as the example,

python train.py --cuda -d coco --root path/to/coco -m yolox_s -bs 16 -size 640 --wp_epoch 3 --max_epoch 300 --eval_epoch 10 --no_aug_epoch 20 --ema --fp16 --multi_scale 

Multi GPU

Taking training YOLOX-S on COCO as the example,

python -m torch.distributed.run --nproc_per_node=8 train.py --cuda -dist -d coco --root /data/datasets/ -m yolox_s -bs 128 -size 640 --wp_epoch 3 --max_epoch 300  --eval_epoch 10 --no_aug_epoch 20 --ema --fp16 --sybn --multi_scale --save_folder weights/ 

Test YOLOX

Taking testing YOLOX-S on COCO-val as the example,

python test.py --cuda -d coco --root path/to/coco -m yolox_s --weight path/to/yolox_s.pth -size 640 -vt 0.4 --show 

Evaluate YOLOX

Taking evaluating YOLOX-S on COCO-val as the example,

python eval.py --cuda -d coco-val --root path/to/coco -m yolox_s --weight path/to/yolox_s.pth
