How to Learn TensorFlow

Most discussions about machine learning tools end up mentioning TensorFlow, a tool developed by Google. This tool, used by beginners and experts alike, comes with a range of libraries that are useful for machine and deep learning.

In this guide, we show you how to learn TensorFlow. We begin by discussing what you need to know about this tool. Next, we tackle the best resources to learn this tool and answer the common questions that come up when learning TensorFlow.

What You Need to Know About TensorFlow

TensorFlow, which is now in version 2, has an extensive range of features for machine learning applications. As a result, there is quite a lot for you to learn. To help you figure out where to begin, here is a list of essential concepts for beginners:

  • Using Keras: TensorFlow is often used in conjunction with Keras, a Python deep learning API. You should build a good understanding of Keras to properly master TensorFlow. 
  • Loading Data: You should learn how to load data into a TensorFlow program and prepare (clean) the data so that it is ready to be used in your application.
  • Building a Model: After you feel comfortable with Keras and loading data, you should start learning about machine learning models and when they are used. You should then learn to build a model for yourself.
  • Neural Networks: Spend time learning about the different types of neural networks such as Convolutional Neural Networks and Recurrent Neural Networks. You will need to know how to implement each of these neural networks in TensorFlow.
  • Saving Models: You should become comfortable with checkpoints and the SavedModel method to save the machine learning models you have created.

The five points above simply give you a place to start; they’re not meant to be the complete syllabus. TensorFlow has a lot of methods that you can learn. However, as a beginner, there is no need to learn everything about the language. Instead, focus on the fundamentals and then work your way into more advanced concepts as you go.

In terms of specific concepts you should look up, consider researching:

  • TensorFlow and Keras
  • Customization
  • Performance
  • Implementing trees
  • Distributed training
  • Working with text, images, and audio
  • RNNs and CNNs

With an understanding of these topics, you will be on your way to becoming proficient in TensorFlow.

Skills Needed to Learn TensorFlow

To become proficient in TensorFlow, there are a few skills you will need:

  • An understanding of a programming language (e.g. Python).
  • A strong understanding of statistics, algebra, and mathematics.
  • A background working with machine learning.

These three skills are all necessary because TensorFlow is a framework for implementing machine learning, which itself is based on programming and mathematics.

Without the right background knowledge, you will struggle to comprehend many of the methods offered by TensorFlow. Make sure you learn a coding language and brush up on your math and machine learning knowledge before attempting to learn TensorFlow.

Why You Should Learn TensorFlow

TensorFlow is used extensively in machine and deep learning. As a result, if you want to pursue a career in either of these fields having a strong understanding of TensorFlow is incredibly valuable. There are other tools used in machine learning, like PyTorch or Keras, but TensorFlow has proven its value as a core machine learning technology.

TensorFlow was developed by Google to enhance their own machine learning projects. The library has been designed for machine learning development, so you are likely to find a lot of the tools you need to build detailed machine learning algorithms. TensorFlow is fast and efficient, which is important for machine learning programs because they often deal with massive datasets.

Overall, TensorFlow will become an important tool in your machine learning arsenal.

How Long Does it Take to Learn TensorFlow?

If you have some Python and machine learning knowledge, expect to spend a few days learning the basics of TensorFlow. You can reasonably start to build some more intricate models with TensorFlow within a few weeks of study as long as you feel comfortable with Python and the basics of machine learning. To learn enough TensorFlow for a job in machine learning, you will probably need to spend between six and twelve months practicing and refining your skills.

Learning TensorFlow will take more time if you are not familiar with Python or machine learning. Knowledge of both of these fields is essential for understanding TensorFlow. We recommend studying the basics of Python and machine learning before you approach TensorFlow.
