ERRO _copy not supported yet

KangolHsu commented 6 years ago

By adding code in https://github.com/Tencent/ncnn/blob/307a77f04be29875f40d337cfff6df747df09de6/tools/mxnet/mxnet2ncnn.cpp#L748


        else if (n.op == "_copy")
        {
            fprintf(pp, "%-16s", "BinaryOp");
        }

        fprintf(pp, "%-16s", "UnaryOp");

    }

that's it

copy 是一个什么操作呢，这个怎么定义 @lovehuanhuan

datafarmers commented 5 years ago

@lovehuanhuan unary_op_copy 这个操作你是怎么定义的？

loscheris commented 5 years ago

I tried @KangolHsu 's method, but it gives different prediction results for the same image each time. I also attempted @lovehuanhuan 's method, unfortunately it leads to compilation error, as unary_op_copy is not defined. I finally solved the problem by combining both ideas: which adds 

else if (n.op == "_copy")
{
fprintf(pp, "%-16s", "UnaryOp");
}

to mxnet2ncnn.cpp line 912

AI-LLM2 commented 5 years ago

@loscheris 我按照你给出的方法，修改的mxnettoncnn的代码，还是会报错误，请问insightface怎么在ncnn中运行？ Detection Time: 0.0985302s Detection Time: 0.182536s layer _copy not exists or registered network graph not ready find_blob_index_by_name data failed find_blob_index_by_name fc1 failed 段错误 (核心已转储)

cyrusbehr commented 5 years ago

@lovehuanhuan any updates? You didn't provide a definition for unary_op_copy in your fix

nihui commented 5 years ago

_copy conversion implemented in https://github.com/Tencent/ncnn/commit/d67d2531ae5c630757d0144359a31701af8de9f6
