TensorFlow Example

Understanding Tensorflow’s example demonstrates the practical application of Deep Learning concepts, aiding in model creation and problem-solving. Familiarity with its use enhances proficiency in Machine Learning development. Suppose we want to build a model that can classify images of fruits. Here is an example using TensorFlow:

In this example, we first import the TensorFlow library. Then, we define two constant tensors, x and y, with the values 2.0 and 3.0, respectively. We use the tf.add() function to add these tensors, creating a new tensor z.

Next, we create a TensorFlow session using the tf.Session() context manager. We can run the computational graph within this session by calling the sess.run() function and pass in the tensor z as an argument. The session evaluates the value of z and returns the result, which we store in the result variable.

Finally, we print out the result, which should be 5.0, as 2.0 + 3.0 = 5.0.
