Hi,
I try to output optimizer.state_dict() but got this one:
{'state': {}, 'param_groups': [{'params': [2131814292216, 2131814292288, 2131814292360], 'nesterov': False, 'weight_decay': 0, 'dampening': 0, 'momentum': 0, 'lr': 0.1}]}

And after backward and have a update, optimizer.state_dict() doesn’t have a change.
model = LinearNetwork()
random_input
random_output
optimizer = SGD(params = model.parameters(), lr=0.1)
loss = MSELoss()
optimizer.zero_grad()
output = model(random_input)
loss = loss(output, random_output)
loss.backward()
optimizer.step()

Do you have any ideas?
