Stride Explorer
Tensors don't store grids; they store lines and use "strides" to jump through them.
Key Insight
A tensor is a view into a flat storage buffer. By changing strides, PyTorch can "re-shape" data instantly without moving a single byte.
Why This Matters
Understanding strides explains why some operations (like .view()) fail and why others (like .transpose()) are free. It is the secret to writing fast, memory-efficient code.
