Mediumauto-graded

Build convolutional layers from raw tensor operations — implementing forward passes with cross-correlation and learnable filters.

Check your answer

The grader verifies properties of your implementation, so a correct solution written differently from ours still passes.

pip install torchleet

from torchleet import check
