A PyTorch implementation of MobileNetV3

I retrain the mobilenetv3 with some novel tricks and timm. I also provide the train code, pre-training weight and training logs on this project.

You should use torch.load to load the model.

from mobilenetv3 import MobileNetV3_Small, MobileNetV3_Large

# MobileNetV3_Small
net = MobileNetV3_Small()
net.load_state_dict(torch.load("450_act3_mobilenetv3_small.pth", map_location='cpu'))

# MobileNetV3_Large
net = MobileNetV3_Large()
net.load_state_dict(torch.load("450_act3_mobilenetv3_large.pth", map_location='cpu'))

You could reproduce the model by the code.

nohup python -u -m torch.distributed.run --nproc_per_node=8 main.py --model mobilenet_v3_small --epochs 300 --batch_size 256 --lr 4e-3 --update_freq 2 --model_ema false --model_ema_eval false --use_amp true --data_path /data/benchmarks/ILSVRC2012 --output_dir ./checkpoint &

This is a PyTorch implementation of MobileNetV3 architecture as described in the paper Searching for MobileNetV3.

Some details may be different from the original paper, welcome to discuss and help me figure it out.
