What are PyTorch tensors and how are they used in deep learning?

PyTorch tensors are multi-dimensional arrays that are used to store data in deep learning. They are similar to NumPy arrays but can be used on GPUs for faster computation.

Can you explain how to create a tensor in PyTorch?

Sure! You can create a tensor in PyTorch using the torch.tensor() function. For example, torch.tensor([1, 2, 3]) creates a 1D tensor.

What are the advantages of using tensors over regular arrays?

Tensors provide better performance for deep learning tasks, especially on GPUs. They also support automatic differentiation, which is crucial for training neural networks.

How do I perform operations on tensors?

You can perform various operations like addition, multiplication, and more using built-in functions. For example, tensor1 + tensor2 adds two tensors element-wise.
