## 3.Start execute the inference:

sh run_efficientnet-b8.sh

or 

python3.7 main.py --model=/data/hwwheel123/model/efficientnet-b8.om --image_size='672,672,3' --inputs='images:0' --outputs='Softmax:0' --precision=fp16


## 4.ATC offline model generate (optional):

1.download  efficientnet-b8 model(.pb) URL: obs://hwwheel23/efficientnet-b8.pb 

2.atc --model=$MODEL_DIR/efficientnet-b8.pb --framework=3 --input_shape='images:1,672,672,3' --output=$MODEL_DIR/efficientnet-b8 --mode=0 --out_nodes='Softmax:0' --soc_version=Ascend310  --input_fp16_nodes=images --output_type=FP16
