Hi @muchen_qingyang,
fpn_ssd_mobilenet-v2 models produced by eIQ Toolkit are not directly usable on SeekFree OpenART mini, even if they are converted to .tflite. This is because eIQ Toolkit trains and converts models for NXP i.MX MPU devices, while object detection models such as fpn_ssd_mobilenet-v2 rely on full TensorFlow Lite runtimes.

Edwin.
