Sound Classifier ERROR (-8)

AworkingM · January 27, 2022, 9:28pm

Hello,
I am using ESP32 for Sound Clasification. I have this error:

ERR: Failed to run classifier (-8)

It worked just fine until I inserted Blutooth Serial into the program. Maybe RAM is nos enough for both programs.

I dont know how to solve this…Please Help!

Could tell me which ESP32 board you are using?
Also I can see several projects under your account, can you tell me which one your are using for this please?

This error code mean EI_IMPULSE_ALLOC_FAILED = -8,:

typedef enum {
    EI_IMPULSE_OK = 0,
    EI_IMPULSE_ERROR_SHAPES_DONT_MATCH = -1,
    EI_IMPULSE_CANCELED = -2,
    EI_IMPULSE_TFLITE_ERROR = -3,
    EI_IMPULSE_DSP_ERROR = -5,
    EI_IMPULSE_TFLITE_ARENA_ALLOC_FAILED = -6,
    EI_IMPULSE_CUBEAI_ERROR = -7,
    EI_IMPULSE_ALLOC_FAILED = -8,
    EI_IMPULSE_ONLY_SUPPORTED_FOR_IMAGES = -9,
    EI_IMPULSE_UNSUPPORTED_INFERENCING_ENGINE = -10,
    EI_IMPULSE_OUT_OF_MEMORY = -11,
    EI_IMPULSE_NOT_SUPPORTED_WITH_I16 = -12,
    EI_IMPULSE_INPUT_TENSOR_WAS_NULL = -13,
    EI_IMPULSE_OUTPUT_TENSOR_WAS_NULL = -14,
    EI_IMPULSE_SCORE_TENSOR_WAS_NULL = -15,
    EI_IMPULSE_LABEL_TENSOR_WAS_NULL = -16,
    EI_IMPULSE_TENSORRT_INIT_FAILED = -17
} EI_IMPULSE_ERROR;

So indeed, it is a memory allocation issue.

Regards,

Louis
