Using OpenVINO 2022.1 causes re-download of cached blob every time

[bgro82]

Hi there,

I updated my code to use OpenVINO 2022.1 and now every time I run the script it says "Cached blob is invalid, will download a new one from API."

I am using the following code (essentially a modified version of the gen2-mjpeg-streaming demo):

    # Start defining a pipeline
    pipeline = dai.Pipeline()
    pipeline.setOpenVINOVersion(version=dai.OpenVINO.Version.VERSION_2022_1)
    # Define a source - color camera
    colorCam = pipeline.create(dai.node.ColorCamera)

    if depth:
        mobilenet = pipeline.create(dai.node.MobileNetSpatialDetectionNetwork)
        monoLeft = pipeline.create(dai.node.MonoCamera)
        monoRight = pipeline.create(dai.node.MonoCamera)
        stereo = pipeline.create(dai.node.StereoDepth)
    else:
        mobilenet = pipeline.create(dai.node.MobileNetDetectionNetwork)

    colorCam.setPreviewSize(512, 512)
    colorCam.setResolution(dai.ColorCameraProperties.SensorResolution.THE_1080_P)
    colorCam.setInterleaved(False)
    colorCam.setColorOrder(dai.ColorCameraProperties.ColorOrder.BGR)

    mobilenet.setBlobPath(blobconverter.from_zoo("person-vehicle-bike-detection-crossroad-1016", shaves=6, version="2022.1"))
    mobilenet.setConfidenceThreshold(0.5)
    mobilenet.input.setBlocking(False)

Let me know if helpful to provide any other details!
