https://github.com/BVLC/caffe/issues/6550

what I did was make patch on
src/caffe/net.cpp Line 772-785

template <typename Dtype>
void Net<Dtype>::CopyTrainedLayersFrom(const string& trained_filename) {
#ifdef USE_HDF5

  if (H5Fis_hdf5(trained_filename.c_str())) {
    CopyTrainedLayersFromHDF5(trained_filename);
  } else {
    CopyTrainedLayersFromBinaryProto(trained_filename);
  }
#else
  CopyTrainedLayersFromBinaryProto(trained_filename);
#endif
