Caffe_ undefine in Matlab on Win10

[Dewey]

Hi,

I've build the Windows Branch of Caffe on my Windows 10 machine with Matlab R2015b. I only built Matlab since I'll need it just for training.

$ ./scripts/build_win.cmd

-- Building without python. Prebuilt dependencies will default to Python 2.7

-- Boost version: 1.61.0

...

The build, test and install works without problem, I get some warnings, but no errors as far as I can see.

Now if i try to run `caffe.run_tests()` in Matlab from C:\Projects\caffe\matlab, I get the following error:

>> caffe.run_tests()

Undefined function or variable 'caffe_'.

Error in caffe.set_mode_cpu (line 5)

caffe_('set_mode_cpu');

Error in caffe.run_tests (line 6)

caffe.set_mode_cpu();

I was wondering why my mex file is in C:\Projects\caffe\matlab\+caffe\private\Release\caffe_.mexw64

I've already added the following paths to Matlab

C:\Projects\caffe\include

C:\Projects\caffe\matlab

Has anyone an idea how I get caffe_ into matlab.

Thanks for your help, let me know if you need more information.

Hi I am having the same error. I tried adding the folder in which mex64 is present to the path but as it contains a '+' symbol I was unable to so. Copying the file to caffe/build/matlab/release resulted in a new error

 Invalid MEX-file 'C:\Users\..\..\..\..\caffe\build\Matlab\Release\caffe_.mexw64': The specified module

could not be found..

Were you able to solve the issue?

copy caffe\matlab\+caffe\private\Release\caffe_.mexw64 file  and paste into caffe\matlab\+caffe\private\
