I’ve just read the project requirements, you probably use PyTorch version 0.3.1 as recommended? Then I think this answer might be relevant.
Try to wrap your tensors data_1
and hidden_1
in torch.Variable()
calls, maybe that will work.
PyTorch versions prior to 0.4.0 used Variable
to indicate that a Tensor
can be “backwarded” upon, whereas normal Tensor
s cannot.
