The function tf. get_variable() returns the existing variable with the same name if it exists, and creates the variable with the specified shape and initializer if it does not exist.

What is the difference between TF variable and TF Get_variable?

First is that tf. Variable will always create a new variable, whereas tf. get_variable gets an existing variable with specified parameters from the graph, and if it doesn’t exist, creates a new one.

What is TF assign?

The tf. assign() operator is the underlying mechanism that implements the Variable. assign() method. It takes a mutable tensor (with tf. *_ref type) and a new value, and returns a mutable tensor that has been updated with the new value.
