The GetDefaultSession() command returns a Session object corresponding to the default session for the current thread.

This function is part of the DeepLearning package, so it can be used in the short form GetDefaultSession(..) only after executing the command with(DeepLearning). However, it can always be accessed through the long form of the command by using DeepLearning[GetDefaultSession](..).

The DeepLearning[GetDefaultSession] command was introduced in Maple 2018.
