cube AI generated code error

[LKan.1]

When trying to use ai_network_ai_params, I get this error during the build process(my model name is sine_model). How do you fix this?

Build error message:

X-Cube-AI version: 7.0.0

STM32CubeIDE version: 1.7.0

board: B-L475E-IOT01A2 (STM32L475VGT6 MCU)

I have the same problem, did anyone found a solution?

I still have the same issue, did anyone find a solution so far?

TEMPORARY Workaround: Downgrade X-Cube-AI package to version 5.2.0

--> Errors were resolved.

However, a solution for the current version 7.0.0 would be very much appreciated!

I installed the version 5.2.0 and made the firmware of Openmv Camera again, but I have the same error as before. So, there must be another problem, not the version as you said.

[DatTran]

ai_network_params ai_params = {AI_SINE_MODEL_DATA_WEIGHTS(ai_sine_model_data_weights_get()), AI_SINE_MODEL_DATA_ACTIVATIONS(activations)};

to

ai_network_params ai_params = AI_NETWORK_PARAMS_INIT(AI_SINE_MODEL_DATA_WEIGHTS(ai_sine_model_data_weights_get()), AI_SINE_MODEL_DATA_ACTIVATIONS(activations));

Because you use the initialization of ver 5.2.0 instead of version 7.0.0

[HElah.1]

I explain what I've done, then you can do it for your project as you need, if your project is a little bit different.

Now, I know what the problem was. I used this version X-CUBE-AI.6.0.0 and after that I added the STM32Cube.AI library to OpenMV, what I forgot to do. So, that was my problem. That was my fault and I didn’t do the following step:

1.4 Step 2 - Add the STM32Cube.AI library to OpenMV

But there is no need to use this version 5.2.0.
