hobbitgrad
hobbitgrad is a tiny educational autograd library written in pure Python. It includes a small NDArray, a Tensor type with backpropagation, a linear layer, SGD, and mean squared error loss.
Install
pip install hobbitgrad
Example
from hobbitgrad import Linear, SGD, Tensor, mse
x = Tensor([[0, 0], [0, 1], [1, 0], [1, 1]])
y = Tensor([[0], [0], [0], [1]])
model = Linear(2, 1)
optimizer = SGD(model.parameters(), lr=0.1)
for _ in range(100):
pred = model.forward(x)
loss = mse(pred, y)
loss.backward()
optimizer.step()
optimizer.zero_grad()
print(loss.data.data[0])
Current Scope
hobbitgrad currently supports a small set of tensor operations, broadcasting, matrix multiplication, scalar reductions, a linear layer, SGD, and MSE loss.
