Is HeyTensor right for you?
A good fit for
ML engineers debugging Conv2d, Linear, and chained architecture shape errors who want local preflight reports before training.
Before you choose
Tensor Preflight is a $29 one-time ZIP purchase rather than a recurring monthly plan; no USD monthly tiers are published.
PyTorch shape debugging
HeyTensor combines a free online calculator for layer output shapes with Tensor Preflight, a downloadable toolkit to inspect forward-pass shapes locally before training.

Frequently asked questions
How do I calculate Conv2d output shape?
Site FAQ documents the standard floor formula for height and width given padding, dilation, kernel, and stride.
Why does PyTorch say mat1 and mat2 shapes cannot be multiplied?
FAQ explains the mismatch usually comes from Linear in_features not matching flattened input size and suggests tracing shapes.
