NumPy vs TensorFlow: What are the differences?

# Introduction
In the world of data science and machine learning, two popular libraries that are commonly used are NumPy and TensorFlow. Both libraries have their own strengths and are designed for specific purposes, but there are key differences that set them apart from each other.

1. **Primary Use**: NumPy is primarily used for numerical computing and array operations in Python, providing support for large, multi-dimensional arrays and matrices along with a collection of mathematical functions to operate on these arrays. On the other hand, TensorFlow is an open-source machine learning framework that is designed for creating and training deep learning models, offering functionalities for building neural networks and optimizing them through algorithms like backpropagation.

2. **Computation Graphs**: TensorFlow operates on computation graphs, where operations are defined as nodes and data flows as edges between these nodes. This graph-based approach allows for efficient computation and optimization of complex neural networks, making it suitable for tasks that involve deep learning and large-scale data processing. In contrast, NumPy does not employ computation graphs and focuses more on array manipulation within Python, making it better suited for general numerical computations.

3. **Ease of Use**: NumPy provides a simple and straightforward interface for performing array operations and mathematical computations, making it easy to get started with for beginners in Python programming. TensorFlow, however, comes with a steeper learning curve due to its complex architecture and the need to understand concepts like tensors, sessions, and variables for building and training deep learning models effectively.

4. **Hardware Acceleration**: TensorFlow is optimized for running computations on CPUs and GPUs, making it well-suited for leveraging the parallel processing power of modern hardware to speed up the training and inference processes in deep learning models. NumPy, while efficient for numerical computations in Python, may not offer the same level of hardware acceleration for large-scale data processing tasks.

5. **Deployment Flexibility**: TensorFlow is designed to support deployment of machine learning models in various environments, including mobile devices, web applications, and cloud platforms, allowing for seamless integration of deep learning models into real-world applications. NumPy, being a fundamental library in Python, lacks the specialized features for model deployment and may require additional frameworks or tools for deploying machine learning models effectively.

In Summary, NumPy and TensorFlow are both powerful libraries in Python that serve different purposes, with NumPy being ideal for numerical computations and array operations, while TensorFlow excels in building and training deep learning models with optimized computation graphs and hardware acceleration capabilities.

    What is NumPy?

    Besides its obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide variety of databases.

    What is TensorFlow?

    TensorFlow is an open source software library for numerical computation using data flow graphs. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) communicated between them. The flexible architecture allows you to deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device with a single API.
