使用paddle_lite_opt转化用ppyolo_r18vd训练导出的模型

paddle_lite_opt --valid_targets=arm --optimize_out_type=naive_buffer --model_file=../__model__ --param_file=../__params__  --optimize_out=../opt --record_tailoring_info=true

提示错误:

WARNING: Logging before InitGoogleLogging() is written to STDERR E0828 10:50:40.061033 29392 opt_base.cc:445] Error: This model is not supported, because 1 ops are not supported on 'arm'. These unsupported ops are: 'matrix_nms'.
