Unable to export YOLOv8 model using aidge_export_cpp

I am trying to export Yolov8 model. My code is given below

import aidge_core
import aidge_onnx
import aidge_export_cpp
import numpy as np

model = aidge_onnx.load_onnx("yolov8n.onnx")

aidge_core.expand_metaops(model, recursive=True)


model.set_datatype(aidge_core.dtype.float32)
model.set_backend("cpu")


model.compile("cpu", aidge_core.dtype.float32, dims=[[1,3,640,640]])

scheduler = aidge_core.SequentialScheduler(model)

scheduler.generate_scheduling()

aidge_core.export_utils.scheduler_export(
        scheduler,
        "myexport",
        aidge_export_cpp.ExportLibCpp,
        memory_manager=aidge_core.mem_info.generate_optimized_memory_info,
        memory_manager_args={"stats_folder": "myexport/stats", "wrapping": False }
)

But I am getting this error

Can anyone guide me how can i fix this issue?
