prototxt is the file extension for Protocol Buffers messages written in text format. Instead of binary serialization, it uses a form people can read and edit, and it is widely known for being used by the deep learning framework Caffe to define network architectures (deploy.prototxt) and training settings (solver.prototxt). Each layer's name, type, input and output blobs, and parameters are described as nested blocks, while trained weights are stored in a separate .caffemodel binary.
