-khadas@2655b6cbbc01:~/npu/demo$ bash convert_adla.sh+
 ``` ```
  
-Each platform will generate an adla file according to the demo.+If everything works well you will find the converted files below.
  
 ```shell ```shell

 +Converted model is ''xxxx.adla''.
 +
 +<WRAP tip >
 +If you want to convert your own model, just modify script ''adla-toolkit-binary/demo/convert_adla.sh'' and  then execute ''./convert-in-docker.sh'' to convert your model.
 +</WRAP>
 +
 +
 +==== Important parameters ====
 +
 +  * ''model-type'' - Model type used in the conversion.
 +  * ''model(model files)/weights(model weights file)'' - ''model'' parameter must be set. ''weights'' needs to be set when model-type is caffe/darknet/mxnet.
 +  * ''inputs/input-shapes'' - ''inputs''  Input node names. ''input-shapes''  The sizes of input nodes. Need to be set when model-type is pytorch/onnx/mxnet/tensorflow/ tflite/paddle.
 +  * ''outputs'' - Output node names. When model-type is tensorflow, outputs needs to be set.
 +  * ''dtypes'' - Input type, set the type information corresponding to the input (optional).Default ''float32''.
 +  * ''quantize-dtype'' - Quantization type. Currently, it supports ''int8'', ''int16'' and ''uint8'' quantification types.
 +  * ''source-file'' - ''dataset.txt''. The txt file contains paths to the images that need to be quantized. It supports images and npy files.
 +  * ''channel-mean-value'' - The pre-processing parameters are set according to the pre processing methods used during model training. It includes four values, m1, m2, m3, and scale. The first three are mean-value parameters and the last one is the scale parameter. For the input data with three channels (data1, data2, data3), the pre-processing steps are
 +    * Out1 = (data1-m1)/scale
 +    * Out2 = (data2-m2)/scale
 +    * Out3 = (data3-m3)/scale
 +  * ''batch-size'' - Set the batch-size for the adla file after conversion. Currently, the default value is 1.
 +  * ''iterations'' - Optional parameter, if ''dataset.txt'' provides data for multi-groups, and needs to use all data provided for quantization, set ''iterations'' and make sure iterations*batch size = Number of data in the multi-groups.
 +  * ''outdir'' - Directory for the generated. The default value is the current directory.
 +  * ''target-platform'' - Specify the target platform for the adla file, it should be ''PRODUCT_PID0XA003'' for VIM4.
