如何配置不同batch进行模型转换

详细描述问题：

1. 目前配置方式

2. /open_explorer/horizon_model_convert_sample/03_classification/05_efficientnet_lite0_onnx/mapper/efficientnet_lite0_config.yaml中修改配置如下

   1. input_shape: '4x3x224x224'
   2. input_batch: 4

3. 按如上配置不同batch时，实际模型转换有错误

4. 具体log如下

   1. root@52ad98697b08:/open_explorer/horizon_model_convert_sample/03_classification/05_efficientnet_lite0_onnx/mapper# ./03_build.sh

   2. cd $(dirname $0) || exit

   3. config_file="./efficientnet_lite0_config.yaml"

   4. model_type="onnx"

   5. # build model

   6. hb_mapper makertbin --config ${config_file} --model-type ${model_type}
