mxnet insightface模型转rknn出错

用到如下代码转换模型，出现错误，请问大神，是什么原因：
rknn = RKNN()
rknn.config(channel_mean_value='0 0 0 255', reorder_channel='0 1 2', target_platform='rk3399pro')
rknn.load_mxnet(
        symbol='model-symbol.json',
        params='model-0000.params',
        input_size_list=[[3, 112, 112]]
    )
rknn.build(do_quantization=True, dataset='dataset.txt')

rknn.export_rknn('./r100_q.rknn')

# Release RKNN Context
rknn.release()

楼主转成功了嘛？
