How to calculate gradients using tf.GradientTape in TensorFlow in Python

Implementing linear regression with TensorFlow involves manually calculating gradients for model parameters. Using `tf.GradientTape`, gradients are computed for loss functions, allowing for precise control over optimization steps. This approach extends to complex neural networks, custom loss functions, and reinforcement learning, enabling efficient gradient-based optimization.
