Train the model

Download pretrained models

download fishnet150 pretrained model from FishNet150 repo(Model trained without tricks )

download mobilenetv2 pretrained model from MobileNet V2 repo

move them to ./checkpoints/pre-trainedModels/

1.train FishNet150

nohup python main.py --config="cfgs/fishnet150-32.yaml" --b 32 --lr 0.01 --every-decay 30 --fl-gamma 2 >> fishnet150-train.log &

2.train MobileNet V2

nohup python main.py --config="cfgs/mobilenetv2.yaml" --b 32 --lr 0.01 --every-decay 40 --fl-gamma 2 >> mobilenetv2-bs32-train.log &

Commands to train the model:

3Train MobileLiteNet54

python main.py --config="cfgs/MobileLiteNet54-32.yaml" --every-decay 60 -b 32 --lr 0.01 --fl-gamma 3 >>FNet54-bs32-train.log

4Train MobileLiteNet54-SE

python main.py --config="cfgs/MobileLiteNet54-se-64.yaml" --b 64 --lr 0.01  --every-decay 60 --fl-gamma 3 >> FNet54-se-bs64-train.log

5Train FeatherNetA

python main.py --config="cfgs/FeatherNetA-32.yaml" --b 32 --lr 0.01  --every-decay 60 --fl-gamma 3 >> MobileLiteNetA-bs32-train.log

6Train FeatherNetB

python main.py --config="cfgs/FeatherNetB-32.yaml" --b 32 --lr 0.01  --every-decay 60 --fl-gamma 3 >> MobileLiteNetB-bs32--train.log

How to create a submission file

example:

python main.py --config="cfgs/mobilenetv2.yaml" --resume ./checkpoints/mobilenetv2_bs32/_4_best.pth.tar --val True --val-save True

Ensemble

for validation

run EnsembledCode_val.ipynb

for test

run EnsembledCode_test.ipynb

notice:Choose a few models with large differences in prediction results
