In this article, we will see Tensorflow Basics Tutorial With Example | Getting Started With Tensorflow. Machine learning is the complex discipline. But implementing the machine learning models is far less daunting and difficult than it used to be, thanks to the machine learning frameworks—such as Google’s TensorFlow: that ease the process of acquiring data, training models, serving predictions, and future results.

TensorFlow is an open source library for numerical computation and large-scale machine learning. TensorFlow bundles together the slew of machine learning and deep learning (also known as neural networking) models and algorithms and makes them useful by way of the common metaphor. It uses Python to provide the convenient front-end API for building applications with the framework while executing those applications in high-performance C++.

Tensorflow Basics Tutorial

For this example, I am using Jupyter Notebook to perform some Tensorflow practicals. So, if your notebook has not installed the Tensorflow library then you can install it using Anaconda Navigator and find the environment section of Anaconda Navigator. You will see something like this.

Here, if a tensorflow package is uninstalled on your machine, then you can install it from here.

Now, launch a Jupyter Notebook and create a new book and verify that you have installed the tensorflow using the following code in the first cell of Jupyter Notebook.

import tensorflow as tf

Run the cell using the Ctrl + Enter command and see the output.

Tensorflow Basic Syntax

Let’s define the Tensorflow constants using the following code. You need to write that code in the next cell.

app = tf.constant('app')

Here, I have defined the app tensorflow constant and also we have checked the type of that constant. Run the cell See the below output.

Let’s define one more tensorflow constant and see its datatype as well.

dividend = tf.constant('dividend')

See the output below.


Tensorflow Constants

Now, print the constant and see the output.


See the output below.


Print Tensorflow constant

See the datatype of the constant is String. The object is Tensor.

The tf.session in Tensorflow

You can not run any operation in Tensorflow without using the sessions. If you try to add any integers or concat the strings, you need to start a session and then add the operational code and then run that operation. Otherwise, nothing will have happened. Let’s concat the above two strings we have defined earlier. See the following example.

with tf.Session() as sess:
    result = + dividend)

Here, we have used the tf.Session() function to start a session and perform the concat operation between two strings and store that output in the result variable and then print that variable. See the output.

Here, in the output represents the byte literal.

Let’s perform the addition operation computation in Tensorflow. Write the following code in the next cell.

a = tf.constant(10)
b = tf.constant(10)
with tf.Session() as sess:
    result = + b)

Here, we have defined the two constants, which are integers and then we have performed the addition operation inside the tensorflow session and store the output in result variable and display that variable. See the following output.

Create Matrix using Tensorflow

We can create a Matrix using Tensorflow functions like, we have created using NumPy library.

We can create the matrix using tf.fill() method provided by the tensorflow framework. See the following example.

mat = tf.fill((5,5), 21)
with tf.Session() as sess:
    op =

See the output below.


Create Matrix using Tensorflow

In the above code, we have created the 5*5 matrix with the 21 values filled inside each element. Remember, we need to perform any operation inside the tensorflow sessions.

So these are some basics of Tensorflow.
