Keras Github: Clarification on files with v1 in their name

TensorFlow General Discussion

I was browsing through the Keras repository and saw that there were files called training_v1.py and training.py

The flow of the code seems to be different in the two and certain edge cases are handled in training.py but arent in training_v1.py

As a person who uses Tensorflow 2 for building models, I wanted to understand what is the difference and whether I should prefer using one file over the other. Also is there a way to pick which file to use for training

This is present in many other files like callbacks etc. So its a bit confusing

Hi @ashwin_jayaraman

Welcome to the TensorFlow Forum!

tensorflow_v1.py file are compatible with Tensorflow version 1.x and has used TF 1.x apis in its code where training.py file will be compatible with Tensorflow 2.x apis which is the latest version.

It’s is always recommended to use the Tensorflow 2.x file.
