pytorch转rknn后 调用init_runtime失败

1.利用pytorch做模型量化感知训练。
2.成功转换为rknn模型。
3.调用rknn.init_runtime(perf_debug=True)失败

pt转rknn代码

    # Load tensorflow model

    # rknn.load_darknet(model='./yolov3.cfg', weight="./yolov3.weights")
    ret = rknn.load_pytorch(model='/work/models/pt/VGGTCNQnewjit.pt', input_size_list=[[3,96,288]])
    # ret = rknn.load_onnx(model = '/work/models/onnx/epoch_20220721_192x320_320s_yuanban.onnx')
    print('done.........................................')

    # ret = rknn.build(do_quantization=False,pre_compile=True)#True
    if ret != 0:
        print('Build pytorch failed!')
        exit(ret)
    print('done')


    rknn.export_rknn('/work/models/rknn/VGGTCNQnewjit.rknn')

    print('export VGGTCNQnewjit.rknn done')

    exit(0)



运行脚本代码报错
