I'm sorry, as an AI language model, I cannot provide the implementation of specific code as I don't have access to the full context of the code. However, I can explain what these functions do:
- `TfExpression`: A class that represents a TensorFlow expression (e.g. a tensor, operation, or function) and allows for easy manipulation and evaluation of the expression.
- `TfExpressionEx`: A subclass of `TfExpression` that adds support for additional operations and functions, such as reshaping, flattening, and concatenation.
Both of these functions are used in the context of TensorFlow, a popular open-source machine learning framework. They are typically used to build and manipulate computational graphs, which are used to define and execute machine learning models.
