Hi, I am working with oak-ffc-4p. When I execute the following program, it does not reach the script node and the device just closes.

from pathlib import Path

import cv2

import depthai as dai

import numpy as np

import time

picWidth = 1280

picHeight = 800

yolo_v5_path = str((Path(file).parent / Path('/Users/annikaschmidt/Documents/vsCode/yolo7_20epoch_openvino_2022.1_6shave.blob')).resolve().absolute())

GPIO = dai.BoardConfig.GPIO

uartNum = 0

uarts = {

0: {  

    'txPin' : 15,

    'rxPin' : 16,

    'txPinMode' : GPIO.ALT_MODE_2,

    'rxPinMode' : GPIO.ALT_MODE_2,

}

}

pipeline = dai.Pipeline()

def cam(p, socket):

colorCam = p.createColorCamera()

colorCam.setBoardSocket(socket)

colorCam.setPreviewSize(picWidth, picHeight)

colorCam.setInterleaved(False)

colorCam.setFps(9)

colorCam.setResolution(dai.ColorCameraProperties.SensorResolution.THE_800_P)

colorCam.initialControl.setManualFocus(255)

manip = pipeline.create(dai.node.ImageManip)

manip.initialConfig.setResizeThumbnail(416,416,0,0,0)

colorCam.preview.link(manip.inputImage)

return manip.out

detectionNetwork = pipeline.createYoloDetectionNetwork()

detectionNetwork.setConfidenceThreshold(0.5) v

detectionNetwork.setIouThreshold(0.5)

detectionNetwork.setNumClasses(3)

detectionNetwork.setCoordinateSize(4)

anchors = np.array([10, 13, 16, 30, 33, 23, 30, 61, 62, 45, 59, 119, 116, 90, 156, 198, 373, 326])

detectionNetwork.setAnchors(anchors)

anchorMasks52 = np.array([0, 1, 2])

anchorMasks26 = np.array([3, 4, 5])

anchorMasks13 = np.array([6, 7, 8])

anchorMasks = {

"side52": anchorMasks52,

"side26": anchorMasks26,

"side13": anchorMasks13

}

detectionNetwork.setAnchorMasks(anchorMasks)

detectionNetwork.setBlobPath(yolo_v5_path)

detectionNetwork.setNumNCEPerInferenceThread(1)

detectionNetwork.setNumInferenceThreads(2)

detectionNetwork.input.setBlocking(False)

pyserial = """

node.io['detections'].get()

node.warn("hello")

"""

script = pipeline.create(dai.node.Script)

script.setProcessor(dai.ProcessorType.LEON_CSS)

script.setScript(pyserial)

cam(pipeline, dai.CameraBoardSocket.CAM_A).link(detectionNetwork.input)

cam(pipeline, dai.CameraBoardSocket.CAM_B).link(detectionNetwork.input)

detectionNetwork.out.link(script.inputs["detections"])

config = dai.Device.Config()

config.board.gpio[uarts[uartNum]['txPin']] = GPIO(GPIO.OUTPUT, uarts[uartNum]['txPinMode'])

config.board.gpio[uarts[uartNum]['rxPin']] = GPIO(GPIO.INPUT, uarts[uartNum]['rxPinMode'])

config.board.uart[uartNum] = dai.BoardConfig.UART()

config.version = config.version.VERSION_2021_4

with dai.Device(config) as device:

device.startPipeline(pipeline)

while not device.isClosed():

    time.sleep(1)

This behavior seems to be caused by this line detectionNetwork.out.link(script.inputs["detections“]). Do you know what the issue could be?

Thank you for your help
