Build the Google protobuf library
Protocol Buffers, also known as protobuf, are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. The ONNX files are generated using protobuf to serialize their ONNX model data. This means that Arm NN needs to use protobuf to load and interpret the ONNX files.
Build protobuf using the C++ installation instructions that you can find on the protobuf GitHub.
$ cd $BASEDIR/protobuf $ git submodule update --init --recursive $ ./autogen.sh $ ./configure --prefix=$BASEDIR/protobuf-host $ make
Arm has tested version 3.5.2. Other versions might work, too.
Duration: About 15 minutes.
Next, copy the built program and its libraries and documentation, to the correct locations using this command:
$ make install
