PyTorch is an open-source deep learning framework that enables fast and flexible development of machine learning models. It provides tools for building and training neural networks efficiently, with support for dynamic computation graphs, GPU acceleration, and seamless integration with Python and C++ workflows.

Features of PyTorch:

• Supports building and training neural networks with dynamic computation graphs.
• Optimized for high-performance computing with GPU acceleration.
• Compatible with popular deep learning libraries, including torchvision, torchaudio, and torchtext.
• Provides easy-to-use APIs for both Python and C++ development.
• Supports distributed training across multiple GPUs and nodes.
• Open-source and actively maintained, widely used for research and production applications.

To check the installed version of PyTorch on Ubuntu 22.04, run these commands in your environment:

$ sudo su
$ sudo apt update
$ cd /opt/pytorch
$ activate-pytorch
$ python -c "import torch; print(f'PyTorch version: {torch.__version__}'); print(f'CUDA available: {torch.cuda.is_available()}'); print(f'Installation path: {torch.__file__}')"
