## Migrate to TF2
> [!CAUTION] > **Caution:** This API was designed for TensorFlow v1. Continue reading for details on how to migrate from this API to a native TensorFlow v2 equivalent. See the [TensorFlow v1 to TensorFlow v2 migration guide](https://www.tensorflow.org/guide/migrate) for instructions on how to migrate the rest of your code. Not compatible with eager execution and [`tf.function`](https://www.tensorflow.org/api_docs/python/tf/function). In particular, Graph collections are deprecated in TF2. Instead please create a [`tf.Module`](https://www.tensorflow.org/api_docs/python/tf/Module) container for all your model state, including variables. You can then list all the trainable variables in your [`tf.Module`](https://www.tensorflow.org/api_docs/python/tf/Module) through the `trainable_variables` attribute.

## Description When passed `trainable=True`, the `Variable()` constructor automatically adds new variables to the graph collection `GraphKeys.TRAINABLE_VARIABLES`. This convenience function returns the contents of that collection.


| ## Args || |---|---| | `scope` | (Optional.) A string. If supplied, the resulting list is filtered to include only items whose `name` attribute matches `scope` using `re.match`. Items without a `name` attribute are never returned if a scope is supplied. The choice of `re.match` means that a `scope` without special tokens filters by prefix. |



| ## Returns || |---|---| | A list of Variable objects. ||
