► Introduction to PyTorch | Course on neural networks with PyTorch.

PyTorch — это как сумасшедший путеводитель в мире нейронных сетей. Он подсказывает, что математика может быть веселой! Процессор или GPU? Не стесняйтесь! Это все о нейронных связях и вычислениях. Переходите на GPU, когда нужны скорость и мощь. Подписывайтесь и готовьтесь к волшебству! 🧠🚀

In this video, Sergey Dubinin provides a brief introduction to the basic features of the PyTorch library. This includes discussion on the autograd features and the functionality of performing calculations on a graphical processor.

Automation and Differentiation 🧮

When working with the PyTorch library, it’s important to acknowledge two primary distinctions: automatic differentiation and the ability to conduct calculations on a graphical processor (GPU).


PyTorch implements automatic differentiation, making it an attractive option when working with neural networks compared to libraries such as NumPy.

Graphical Processor UsageEnables computations on a GPU

Installation and Setup 🛠️

To install the PyTorch library, navigate to your Jupyter notebook, then use the command !pip install torch. Once installed, you can import the library and begin utilizing its full range of features.

Step by Step

Ensure the library is installed correctly by executing the command !pip install torch. Then import the library to your project with the statement, import torch.

A Comparison with NumPy 🌐

The PyTorch library is often likened to NumPy due to similarities in their syntax and concentric functionalities. Both libraries can be regarded as twins due to their shared set of functions, methods, and even naming conventions.

PyTorch Elements 📊

The fundamental building block in PyTorch is the tensor, which is essentially a multidimensional array. These tensors are crucial for numerical computations and are a pivotal concept in PyTorch.

Tensor Basics

When declaring a tensor, the library provides the flexibility to specify additional arguments such as data type and differentiation.

import torch
tensor = torch.tensor([1, 2, 3, 4, 5], dtype=torch.float32, requires_grad=True)

Operating with Tensors 🔄

In PyTorch, you can perform various operations with tensors, such as reshaping, multiplying, and adding. This provides a high level of flexibility when dealing with multi-dimensional arrays.

Utilizing the Power of PyTorch 🚀

When utilizing PyTorch, it’s imperative to understand the library’s capacity to utilize both the CPU and GPU. By utilizing the appropriate syntax, users can seamlessly access either or both of these processing units.

Processor Accessibility

PyTorch provides users with the capability to check the availability of both the CPU and the GPU.

# Check the availability of CPU and GPU
print(torch.cuda.is_available(), torch.cuda.is_available())

To leverage the full potential of PyTorch, users are advised to engage in further exploration beyond this brief overview. Projects such as Sergey Dubinin’s comprehensive course provide a fitting platform to acquire an in-depth understanding of PyTorch.

By incorporating these foundational concepts, users will have laid a sturdy groundwork for their subsequent ventures into PyTorch. As such, this meticulous understanding will undoubtedly pave the way for prosperous outcomes in the realm of neural networks powered by PyTorch.
