"""Functions for Python 2 vs. 3 compatibility.
"""Compatibility functions.
## Conversion routines
In addition to the functions below, `as_str` converts an object to a `str`.
The `tf.compat` module contains two sets of compatibility functions.
## Tensorflow 1.x and 2.x APIs
The `compat.v1` and `compat.v2` submodules provide a complete copy of both the
`v1` and `v2` APIs for backwards and forwards compatibility across TensorFlow
versions 1.x and 2.x. See the
[migration guide](https://www.tensorflow.org/guide/migrate) for details.
## Utilities for writing compatible code
Aside from the `compat.v1` and `compat.v2` submodules, `tf.compat` also contains
a set of helper functions for writing code that works in both:
* TensorFlow 1.x and 2.x
* Python 2 and 3
## Types
The compatibility module also provides the following types:
## Type collections
The compatibility module also provides the following aliases for common
sets of python types:
* `bytes_or_text_types`
* `complex_types`
