Hands-On Convolutional Neural Networks with TensorFlow

Variables

How do we write this all out in TensorFlow code? Let's start by creating our weights and biases. In TensorFlow, if we want to create some Tensors that can be manipulated by our code, then we need to use TensorFlow variables. TensorFlow variables are instances of the tf.Variable class. A tf.Variable class represents a tf.Tensor object that can have its values changed by running TensorFlow operations on it. Variables are Tensor-like objects, so they can be passed around in the same ways Tensors can and any operation that can be used with a Tensor can be used with a variable.

To create a variable, we can use tf.get_variable(). When you call this function, you must supply a name for your variable. This function will first check that ...
