💥💥💥 How to learn TensorFlow?



  • Python: Before you even start studying TensorFlow, you should be familiar with the Python programming language. Python is the most widely used language for TensorFlow, and it offers many libraries and tools for data analysis, visualization, and manipulation. You can learn Python from various online courses, books, or tutorials, such as Learn Python or Python for Everybody.
  • Foundations of Neural Networks: Since TensorFlow is a deep learning framework, it helps a lot to have a conceptual understanding of neural networks. Neural networks are composed of layers of artificial neurons that can learn from data and perform various tasks, such as classification, regression, generation, and more. You can learn the basics of neural networks from courses, books, or videos, such as Neural Networks and Deep Learning or 3Blue1Brown’s Neural Networks playlist.
  • Building Models with the Keras Sequential API: Keras is a high-level API that makes it easy to build and train models in TensorFlow. The Keras Sequential API allows you to create models by stacking layers in a linear fashion. You can learn how to use the Keras Sequential API from the official [TensorFlow tutorials], such as [TensorFlow 2 quickstart for beginners] or [Image classification].
  • Data Preprocessing: Data preprocessing is an essential step in any machine learning project. It involves transforming, cleaning, and augmenting the data to make it suitable for the model. TensorFlow offers multiple data tools to help you load, manipulate, and visualize data, such as tf.data, tf.io, tf.image, and more. You can learn how to use these tools from the official [TensorFlow guides], such as [Load and preprocess data] or [Data augmentation].
  • Keras Functional API, DataTypes, and Arithmetic Operators: The Keras Functional API is another way to create models in TensorFlow. It allows you to create more complex and flexible models that can have multiple inputs, outputs, or branches. You can learn how to use the Keras Functional API from the official [TensorFlow tutorials], such as [Multi-input and multi-output models] or [Siamese network with a triplet loss]. Additionally, you should also be familiar with the basic data types and arithmetic operators in TensorFlow, such as tensors, variables, constants, gradients, and more. You can learn these concepts from the official [TensorFlow guides], such as [Introduction to tensors] or [Introduction to gradients and automatic differentiation].
  • Advanced Topics: Once you have mastered the basics of TensorFlow, you can explore more advanced topics, such as distributed training, custom layers, custom training loops, model optimization, model deployment, and more. You can learn these topics from the official [TensorFlow tutorials] and [TensorFlow guides], as well as from other sources, such as [TensorFlow Hub], [TensorFlow Model Garden], [TensorFlow Probability], [TensorFlow Federated], and more. You can also find many examples of state-of-the-art research models implemented in TensorFlow, such as [Transformers], [GANs], [BERT], and more.

How do I install TensorFlow on my computer?

There are different ways to install TensorFlow on your computer, depending on your operating system, your hardware, and your preferences. Here are some possible options:

  • Install TensorFlow with pip: This is the easiest and most common way to install TensorFlow. You can use the pip package manager to install TensorFlow and its dependencies. You can choose between the CPU-only version or the GPU version of TensorFlow, depending on whether you have a CUDA-enabled GPU card or not. To install TensorFlow with pip, you need to have Python 3.9–3.11, pip version 19.0 or higher for Linux and Windows, or pip version 20.3 or higher for macOS. You can follow the official TensorFlow tutorials or TensorFlow guides for detailed instructions on how to install TensorFlow with pip for different operating systems and environments.
  • Run a TensorFlow container: This is another easy way to use TensorFlow without having to install it on your system. You can use Docker to run a TensorFlow container that is already configured to run TensorFlow. You can choose between the CPU-only version or the GPU version of TensorFlow, depending on whether you have a CUDA-enabled GPU card or not. To run a TensorFlow container, you need to have Docker installed on your system. You can follow the official Docker install guide for detailed instructions on how to run a TensorFlow container for different operating systems and environments.
  • Build from source: This is a more advanced and customized way to install TensorFlow. You can build TensorFlow from source code and specify the options and features you want. You can also enable support for different hardware and software configurations, such as CUDA, TensorRT, MKL, etc. To build TensorFlow from source, you need to have Bazel, MSYS2, Visual C++ Build Tools 2019, and other dependencies installed on your system. You can follow the official TensorFlow source guide for detailed instructions on how to build TensorFlow from source for different operating systems and environments.

What is the difference between TensorFlow 1 and TensorFlow 2?

The difference between TensorFlow 1 and TensorFlow 2 is a common question among machine learning enthusiasts and developers. TensorFlow is a popular open-source framework for machine learning and deep learning, developed by Google. TensorFlow 1 was released in 2017, and TensorFlow 2 was released in 2019. Here are some of the main differences between the two versions:

  • Eager execution: TensorFlow 2 enables eager execution by default, which means that the code is executed immediately as it is written, without creating a static graph first. This makes debugging and prototyping easier and more intuitive. TensorFlow 1 requires explicit graph creation and session management, which can be cumbersome and error-prone. However, TensorFlow 1 also supports eager execution as an experimental feature, and TensorFlow 2 also supports graph mode via the tf.function decorator, which can improve performance and portability.
  • Keras integration: TensorFlow 2 adopts Keras as the high-level API for building and training models, making it more user-friendly and consistent. Keras is a widely used and well-documented framework that simplifies common tasks such as data preprocessing, model construction, regularization, and evaluation. TensorFlow 1 also supports Keras, but as a separate package that is not fully integrated with the core TensorFlow APIs.
  • API cleanup: TensorFlow 2 removes or deprecates many redundant, inconsistent, or low-level APIs from TensorFlow 1, making it more concise and coherent. For example, TensorFlow 2 removes tf.app, tf.flags, and tf.logging in favor of the absl-py library, rehomes projects that lived in tf.contrib, and moves lesser used functions into subpackages like tf.math. TensorFlow 2 also replaces some APIs with their updated equivalents, such as tf.summary, tf.keras.metrics, and tf.keras.optimizers.
  • Distributed training: TensorFlow 2 simplifies the process of distributed training, which allows you to leverage multiple devices or machines to speed up your model training and inference. TensorFlow 2 provides the tf.distribute API, which abstracts away the details of distribution strategies and offers a consistent interface for single or multiple GPUs, TPUs, or CPUs. TensorFlow 1 also supports distributed training, but with more complex and lower-level APIs, such as tf.distribute.ClusterSpec, tf.distribute.Server, and tf.distribute.Strategy.

These are some of the major differences between TensorFlow 1 and TensorFlow 2. If you want to learn more, you can check out the official TensorFlow tutorials or TensorFlow guides, or some of the web search results I found for you, such as TensorFlow 1.x vs TensorFlow 2 - Behaviors and APIs, Tensorflow 1.0 vs. Tensorflow 2.0: What’s the Difference?, or TensorFlow vs TensorFlow 2: Which is Better?. I hope this helps you understand the difference between TensorFlow 1 and TensorFlow 2.
