No source available for "ai_platform_network_process() at 0x8xxxxx"

[PGaja.1]

Hi,

We are trying a very simple deep neural network model with 20 inputs and 3 outputs and want to generate inferences in real-time. We are following the instructions from the document "Getting started with X-CUBE-AI Expansion Package for Artificial Intelligence (AI)" numbered UM2526 with X Cube AI 7.1.0 with STM32CubeMX.

Has anyone encountered the same error?

Thanks in advance.

At what point, exactly, do you get that message?

It sounds like you're using the debugger, and trying to step into or break within a function called ai_platform_network_process() ?

So the first question is: do you have the source code for that function?

If you don't have the source code, then "no source available" is obviously true!

I have not made any changes to file generated by STM32 CubeMX. Also, this is the code that we are using for inference in the neural network:

 static ai_handle network = AI_HANDLE_NULL;

 ai_network_report report;

 ai_bool res;

 ai_error err;

 const ai_u16 batch_size = 1;

 err = ai_network_create(&network, AI_NETWORK_DATA_CONFIG);

 AI_ALIGNED(4) static ai_u8 activations[AI_NETWORK_DATA_ACTIVATIONS_SIZE];

 const ai_network_params params = {

  AI_NETWORK_DATA_WEIGHTS(ai_network_data_weights_get()),

  AI_NETWORK_DATA_ACTIVATIONS(activations) };

 nbatch = ai_network_run(network, &ai_input[0], &ai_output[0]);

I face with same problem. I imported Keras model and CubeAI tool could analyze the model successfully but it didn't create source file for same function. There is just a declaration for function but no definition.

Could you find any solution for that? If you found, please share with me too.
