What is the concept of PyTorch’s dynamic computational graph?

The PyTorch dynamic computation graph means that in PyTorch, the graph is dynamically constructed, meaning it is rebuilt during each forward propagation. This allows users to dynamically define, modify, and adjust the graph at runtime, without the need to define a static graph beforehand. This feature of a dynamic computation graph makes PyTorch more flexible and convenient for implementing dynamic models like Recurrent Neural Networks (RNN) and Recursive Neural Networks. Additionally, the dynamic computation graph makes debugging and optimizing models simpler and more intuitive.
