RuntimeError: Expected object of scalar type Double but got scalar type Float for argument #2
I have a PyTorch LSTM model and my forward function looks like:

    def forward(self, x, hidden):
        print('in forward', x.dtype, hidden[0].dtype, hidden[1].dtype)
        lstm_out, hidden = self.lstm(x, hidden)
        return lstm_out, hidden


All of the print statements show torch.float64, which I believe is a double. So then why am I getting this issue?

I've cast to double in all of the relevant places already.

Make sure both your data and model are in dtype double.
For the model:
net = net.double()

For the data:
net(x.double())

It has been discussed on PyTorch forum.
