What is a PROTOTXT file?

A PROTOTXT file is a prototype machine learning model created for use with Caffe. It contains an image classification or image segmentation model that is intended to be trained in Caffe. PROTOTXT files are used to create .CAFFEMODEL files.

Caffe (Convolutional Architecture for Fast Feature Embedding) is a deep learning framework that allows users to create image classification and image segmentation models. Initially, users create and save their models as plain text .prototxt files. After a user trains and refines their model using Caffe, the program saves the user's trained model as a CAFFEMODEL file.

PROTOTXT files are serialized using Google's Protocol Buffers serialization library, and they contain:

  • A list of the neural network layers a model contains
  • Each layer's parameters, including its name, type, input dimensions, and output dimensions
  • Specifications for connections between layers

How to open a PROTOTXT file

PROTOTXT files are intended to be used as prototype Caffe (cross-platform) machine learning models. However, because PROTOTXT files are plain text files, you can open and edit them in any text editor if needed.
