--- Neural network library written in Python completely from scratch, using only numpy. ## Usage ``` from pygrad.tensor import Tensor a, b = Tensor(np.random.randn(3, 1)), Tensor(np.random.randn(1, 3)) c = a.mul(b) d = c.exp() d.backward() print(a.grad, b.grad, c.grad) # should output something like # [[-16.51232262 -16.51232262 -16.51232262]] # [[-53.88103349 -53.88103349 -53.88103349]] # [[ 3.50417648 3.50417648 3.50417648] # [15.67424587 15.67424587 15.67424587] # [16.0131011 16.0131011 16.0131011 ]] ``` ## References - - ## Copying This is free and unencumbered software released into the public domain.
