Can some clarify difference between protocol buffer and protoc ?. Googling only shows protocol buffers. I see that naming convention is different for both protobuf-programming language-version and protoc-operating system-86_32. Are they different or same ?
Do i need to install both while working with tensorflow ? Although
protoc --version
is 3.6 but my pip is complaining
tensorflow-gpu 1.7.0 has requirement protobuf>=3.4.0, but you'll have protobuf 2.6.1 which is incompatible.

Google provides a compiler called protoc which can produce output for C++, Java or Python. Other schema compilers are available from other sources to create language-dependent output for over 20 other languages.
Protocol buffers are a combination of the definition language (created in . proto files), the code that the proto compiler generates to interface with data, language-specific runtime libraries, and the serialization format for data that is written to a file (or sent across a network connection).
TL;DR — encoding and decoding string-intensive data in JavaScript is faster with JSON than it is with protobuf. When you have structured data in JavaScript, which needs to be sent over the network (for another microservice for example) or saved into a storage system, it first needs to be serialized.
Protocol buffers, usually referred as Protobuf, is a protocol developed by Google to allow serialization and deserialization of structured data. Google developed it with the goal to provide a better way, compared to XML, to make systems communicate.
"protobuf" or "protocol buffers" is the name of a serialization format and/or associated tooling.
protoc is a specific protobuf tool, specifically Google's implementation of a ".proto" parser and code generator (and a few other things)
".proto" is a schema DSL used for describing the messages you plan to use in your application - it is text based.
The usual process is:
Some tools work the other way around, working from your own types in your platform (the "code first" rather than "contract first" approach)
