After converting the NN model using the Acuity NN Toolkit, the sample code for using the model will be automatically generated. The code is located in path "/Models/{model name}/wksp/ {model_name}_ {type}_nbg_unify". How to convert a model please refer to NN model conversionModel Conversion
The sample code encompasses operations associated with the NN model, along with preprocessing and postprocessing related to the NN model. We need to cross-compile this code into an application that can execute on C3V Linux. Additionally, we should utilize it along with the generated NB file.

When compiling NN-related applications, it is necessary to include SDK's headers and libraries.
Example of SDK Include Includes Path：
| Code Block |
|---|
INCLUDES+=-I$(VIVANTENN_SDK_DIR)/include/ \ -I$(VIVANTENN_SDK_DIR)/include/CL \ -I$(VIVANTENN_SDK_DIR)/include/VX \ -I$(VIVANTENN_SDK_DIR)/include/ovxlib \ -I$(VIVANTENN_SDK_DIR)/include/jpeg |
Example of SDK Link Libraries：

This is an example makefile that just needs to be placed in wksp/ {model_name}_{type}_nbg_unify Folder. And set the relevant VIVIANTE_ SDK_ DIR and TOOLCHAIN can complete the compilation of the app:
