MATLAB wrapper for Windows

[ssakhavi]

Hi,

I wanted to ask that what modifications I must perform on the matcaffe.cpp so it can work for the windows installation you have proposed.

Hi,

I have been able to generate a mex file with the following project: https://github.com/mjmarin/caffe/tree/winmex/build/MSVCmex

I hope you find it useful.

@mjmarin Thank you very much for your information. It is more than welcome, if you can push a PR to my branch.

Any chance the pre-compiled MEX file could make it into the standalone package? It would make for a really easy setup for any newcomers who just want to play a bit with the standard networks in their scripts.

@mjmarin Could you help me? There is something wrong with my caffe.mex64. I can pass the compile. But when I run matcaffe_demo.m.

Invalid MEX-file 'E:\caffe-winmex\matlab\caffe\caffe.mexw64': E:\caffe-winmex\matlab\caffe\caffe.mexw64 is not a valid Win32 application.

My configuration: win8.1 x64 matlab2014a cuda 6.0 vs2012

@CMeteor I'm not an expert but, have you tried to build your MSVS project both in "Win32" and "x64"? Perhaps you selected the wrong one. Sorry for not being able to provide you more help.

@CMeteor The invalid MEX-file messages usually means required dlls are missing. Please check your %PATH% environment variable include the path "caffe/bin". You can use Matlab function "setenv".

Example setenv('PATH', [getenv('PATH') ';CAFFE_INSTALLED_PATH/bin']);

[CMeteor]

@mjmarin @yimingchan Thank you very much. I add the path "caffe/bin" to %PATH% environment variable.everything is OK.

Hi @mjmarin and people, I am new to this. Can you tell me how to run the matlab MEX in more detail? I downloaded the MEX64 file and put it in matlab/caffe/ folder. Is it enough to run the demo in caffe? If not, what else should I do? My error is:

Invalid MEX-file 'D:\caffe-windows\matlab\caffe\caffe.mexw64': The specified module could not be found.

Error in matcaffe_init (line 19) if caffe('is_initialized') == 0

@shuangao Hi, have you solved your problem, i met with the same question。。。。

[iiwindii]

@CMeteor Hi, in the caffe directory , i have not found "caffe/bin"..... can you give some details,,thanks

@shuangao I've met the same problem, did you solve your problem?

[shuangao]

NO. I gave up and turn to python wrapper which is very easy for training and predicting. You can find the tutorial here http://nbviewer.ipython.org/github/BVLC/caffe/tree/master/examples/
