Khronos Group contractor Au-Zone has added their NNEF converter to the Khronos Group NNEF Tools repository. There are now two sets of converters in this repository. The converters provided by the Khronos Group convert between Caffe and TensorFlow. The Caffe converter reads/writes models in protobuf format, while the TensorFlow converter reads/writes the Python script that builds the TensorFlow graph. The converters provided by Au-Zone convert between Caffe2 and TensorFlow, both reading/writing models in protobuf format.
