Error while compilation of mxnet

[salonip]

Your API seems to be exactly what I have been looking for. Just one tiny problem! MXNet is getting terminated during compilation with following error make: * [build/src/operator/softmax_multilabel_output.o] Error 1 make: * Waiting for unfinished jobs.... src/operator/softmax_multilabel_output.cu:8:48: fatal error: ./bx_softmax_multilabel_output-inl.h: No such file or directory

include "./bx_softmax_multilabel_output-inl.h"

                                            ^

compilation terminated.

What I am doing wrong?what file is bx_softmax_multilabel_output-inl.h?

@salonip Oh, this is a stupid mistake I made because I renamed my files.

Could you please rename "softmax_output.h" as "softmax_multilabel_output.h" and in both softmax_multilabel.cc and softmax_multilabel.cu, please change

include "./bx_softmax_multilabel_output-inl.h" to #include "./softmax_multilabel_output-inl.h"

Let me know if this fix your problem. Thanks.

[jimxinbo]

sorry, rename "softmax_output.h" as "softmax_multilabel_output-inl.h" change the name in .cc and .cu files accordingly.

Anyway, I just update these modifications.

[salonip]

Oh !thanks for instant reply.I just checked with you in-case I missed some important renaming or something!Thank you .

Hmm, seems a big deal. I will look into it soon. Btw, why system are you using ? Did you installed cuda correctly?

[salonip]

yes.,cuda is working for Mocha.jl and Mxnet python,Mxnet julia is still issue for me. I am using Ubuntu 14.04 cuda7.0 GPU GeForce GTX 750 Ti

Hi @jimxinbo @salonip

I think this error msg caused by mxnet version mismatch. mxnet itself changes a lot and @jimxinbo 's code is based on outdated version of mxnet. if possible could you please update your implementation ? I am very interesting about multi-label classification.

[janviparikh]

Hi @jimxinbo @haria I am facing a similar issue and really interested in multi label. Would really appreciate it if a fix or workaround for this could be provided. Thanks

[jimxinbo]

@salonip @haria @janvidpa

Sorry for the late response. I just recompile the latest mxnet with the three files for multilabel included, seems everything works out well.

So I checked online about the issue like "error: ‘blockIdx’ was not declared in this scope const int y = blockIdx.x;". I find the following links might help https://devtalk.nvidia.com/default/topic/469150/-solved-code-not-compiling-for-mysterious-reason/ https://devtalk.nvidia.com/default/topic/526156/code-compile-success-in-windows-but-not-linux-/

Seems it's something related to compilation. Current my code was compiled on Windows and there are not complains. This seems a problem on Linux. I will try to find a Linux server to fix it soon. Meantime, if you find any simple tricks to get around, please let me know. Thanks.

@jimxinbo thanks ! will look it up
