I'm working on a ML project with X-Cube-AI version 7.3.0 with the STM32F4DISCOVERY board.
I created the neural network with tensorflow, and the analysis went smooth, the network occupies 25 kb of flash and 8 kb of ram.
This is the neural network summary;
Model: "sequential_8"

However, at runtime when I call the function ai_network_create I obtain an error of tyoe 51 and code 65 which corresponds to AI_ERROR_CREATE_FAILED and to AI_ERROR_CODE_LOCK respectively.
What this code means? Why it happens?
ai_handle network;
ai_error err = ai_network_create(&network, (const ai_buffer*)AI_NETWORK_DATA_CONFIG);
if (err.type != AI_ERROR_NONE)
{
printf("E: AI error in NN creation - type=%d code=%d\r\n", err.type, err.code);
// TODO: error handling
}
else
{
printf("NN successfully created.\n");
}
