问题描述
本人遇到这个问题的环境：
Ubuntu16
CUDA8
Caffe
Matlab2015b
具体环境安装可见个人博客
在编译matlab版本caffe时遇到
安装正常，编译caffe正常，编译matcaffe正常，测试matcaffe也正常，但在用matcaffe训练模型时出现 :
You set your caffe in caffePath.cfg at: ../caffe/matlab

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.
If this problem is reproducible, please submit a Service Request via:
http://www.mathworks.com/support/contact_us/
A technical support engineer might contact you with further information.

问题分析
如果用matlab调试的话，会发现死在：pSolver = caffe_(‘get_solver’, solver_file);
function solver = get_solver(solver_file)
% solver = get_solver(solver_file)
% Construct a Solver object from solver_file
CHECK(ischar(solver_file), 'solver_file must be a string');
CHECK_FILE_EXIST(solver_file);
pSolver = caffe_('get_solver', solver_file);
solver = caffe.Solver(pSolver);
end
也就是在读取solver文件时不认识SGD，没有注册SGD(当然也可能时Adam或其他，看自己用的什么算法)
问题解决
在matlab的caffe_.cpp注册SGD
打开caffe/matlab/+caffe/private/caffe_.cpp
在开头加上
#include "caffe/sgd_solvers.hpp"
namespace caffe {
INSTANTIATE_CLASS(AdaDeltaSolver);
REGISTER_SOLVER_CLASS(AdaDelta);
INSTANTIATE_CLASS(AdaGradSolver);
REGISTER_SOLVER_CLASS(AdaGrad);
INSTANTIATE_CLASS(AdamSolver);
REGISTER_SOLVER_CLASS(Adam);
INSTANTIATE_CLASS(NesterovSolver);
REGISTER_SOLVER_CLASS(Nesterov);
INSTANTIATE_CLASS(RMSPropSolver);
REGISTER_SOLVER_CLASS(RMSProp);
INSTANTIATE_CLASS(SGDSolver);
REGISTER_SOLVER_CLASS(SGD);
}
重新编译，OK
