PyTorch is an open-source, Python-based deep learning framework used for a variety of applications like computer vision, natural language processing, and scientific computing. It's known for its: Flexibility: Offers dynamic computation graphs, allowing for efficient experimentation and customization of models. Imperative programming: Enables easier debugging and understanding of code compared to purely declarative frameworks. Rich ecosystem: Supports various libraries like PyTorch Lightning, Torchvision, and PyTorch Geometric for specific tasks.

Key features of PyTorch:

• Tensors: Multi-dimensional arrays for storing and manipulating data like images, text, and numerical data.
• Automatic differentiation: Tracks operations performed on tensors to efficiently compute gradients and backpropagate errors during training.
• Modules: Reusable building blocks for neural networks, like convolutional layers and recurrent layers.
• Optimizers: Algorithms that update model parameters based on training data to minimize loss..

To check the installation and version of the PyTorch perform the steps below:

• Update the VM with: sudo apt-get update, now follow below steps
• i) sudo su
• ii) cd /root
• iii) Again, update the VM with: sudo apt-get update.
• iv) Now, run the mentioned command to activate the conda environment: conda activate pytorch_env
• v) Run this command to check the version of the PyTorch: conda list pytorch
• vi) To deactivate the conda, run: conda deactivate
