Declaring variables and tensors

Tensors are the primary data structure that TensorFlow uses to operate on the computational graph. Even if now, in TensorFlow 2.x, this aspect is hidden, the data flow graph is still operating behind the scenes. This means that the logic of building a neural network doesn't change all that much between TensorFlow 1.x and TensorFlow 2.x. The most eye-catching aspect is that you no longer have to deal with placeholders, the previous entry gates for data in a TensorFlow 1.x graph.

Now, you simply declare tensors as variables and proceed to building your graph.

A tensor is a mathematical term that refers to generalized vectors or matrices. If vectors are one-dimensional and matrices are two-dimensional, a tensor is n-dimensional (where n could be 1, 2, or even larger).

We can declare these tensors as variables and use them for our computations. To do this, first, we must learn how to create tensors.
