Welcome to the PyTorch Basics guide! Whether you're new to deep learning or just starting with PyTorch, this tutorial will help you get familiar with the essentials. Let's dive in!
Installation 🛠️
To begin, install PyTorch using pip or conda.
pip install torch
📌 Tip: For GPU support, use pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu118
Core Concepts 🧠
- Tensors - Multi-dimensional arrays similar to NumPy's
ndarray
.
⚠️ Example:torch.tensor([[1, 2], [3, 4]])
- Autograd - Automatic differentiation for tracking operations.
🔍 Key feature: Gradient computation viabackward()
method - nn.Module - Neural network building blocks for models.
Quick Start Example 📈
import torch
x = torch.tensor(3.0)
y = x**2
dy_dx = y.backward() # Compute derivative
print(f"Derivative of y = x² at x=3 is {dy_dx}")
🎉 Output: Derivative of y = x² at x=3 is 6.0
