importCaffeNetwork by Matlab 2017a deep learning toolbox

When I tried to use Matlab 2017a Deep Learning Toolbox to import caffe model, it showed errors.

Error using nnet.internal.cnn.caffe.mexcaffe Invalid MEX-file '/home/yunyang/Documents/MATLAB/SupportPackages/R2017a/toolbox/nnet/supportpackages/caffe_importer/+nnet/+internal/+cnn/+caffe/mexcaffe.mexa64': /home/yunyang/Documents/MATLAB/SupportPackages/R2017a/toolbox/nnet/supportpackages/caffe_importer/+nnet/+internal/+cnn/+caffe/mexcaffe.mexa64: undefined symbol: _ZNK6google8protobuf7Message11GetTypeNameEv.

Error in importCaffeNetwork (line 80) readerObj = nnet.internal.cnn.caffe.CaffeModelReader(protofile, 'Datafile', ...

My machine configuration:

Hi Yunyang,

The issue with "importCaffeNetwork" could be due to incompatibility of the protobuf file.

If you export "LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libprotobuf.so.9", MATLAB does not work for deep learning. If you delete this, MATLAB will work correctly.
