 使用ATC模型转换工具进行模型转换时可以参考如下指令:
 
 ```shell
-atc --input_shape="input_1:10,224,224,3" --output=./color_dvpp_10batch --soc_version=Ascend310 --framework=3 --model=./color.pb --insert_op_conf=./aipp.cfg
+atc --input_shape="input_1:-1,224,224,3" --output=./color_dynamic_batch --soc_version=Ascend310 --framework=3 --model=./color.pb --insert_op_conf=./aipp.cfg --dynamic_batch_size="1,2,4,8"
 ```
