@Hashir

If you ask questions, write about the environment in detail.

The error message says:

/opt/movidius/ssd-caffe/build/include/caffe/proto/caffe.pb.h:12:2

This file was generated by a newer version of protoc which is

incompatible with your Protocol Buffer headers. Please update

your headers.

So please try the following.

$ protoc --version
<show protobuf version>

$ sudo apt update
$ sudo apt upgrade
$ protoc --version
<show protobuf version>

$ make install

The version you need depends on whether Ubuntu or Raspbian.

If the above command does not work, try the command below.

Install libprotobuf 3.5.1.

$ cd ~
$ wget https://github.com/google/protobuf/releases/download/v3.5.1/protobuf-all-3.5.1.tar.gz
$ tar -zxvf protobuf-all-3.5.1.tar.gz
$ cd protobuf-3.5.1
$ ./configure
$ sudo make -j1
$ sudo make install
$ cd python
$ export LD_LIBRARY_PATH=../src/.libs
$ python3 setup.py build --cpp_implementation 
$ python3 setup.py test --cpp_implementation
$ sudo python3 setup.py install --cpp_implementation
$ sudo ldconfig
$ protoc --version

$ cd <ncsdk folder path>
$ make install

If you do not do the above command, it is suspected of conflict with pycaffe or other.
