Needless to say, if it has been developed by Google, there already is a large team of software engineers who work on stability improvements continuously.
6. Open Source
The best thing about this machine learning library is that it is open source so anyone can use it as long as they have internet connectivity.
Uses of TensorFlow?
You are using TensorFlow daily but indirectly with applications like Google Voice Search or Google Photos. These are the applications of TensorFlow.
All the libraries created in TensorFlow are written in C and C++. However, it has a complicated front-end for Python. Your Python code will get compiled and then executed on TensorFlow distributed execution engine built using C and C++.
The number of applications of TensorFlow is literally unlimited and that is the beauty of TensorFlow.
