LSTM Error: lstm() received an invalid combination of arguments

1

Hello, I am trying to implement a LSTM but I am getting an error when running the forward function.

I intialized my model like this:

m = nn.LSTM(input_size = 8, hidden_size = 128, num_layers = 1,dropout=0.1,bidirectional=0,batch_first=True)

And then, when doing this:

m.forward(batch[0])

I get the following error:

lstm() received an invalid combination of arguments - got (Tensor, tuple, list, bool, int, float, bool, int, bool), but expected one of:

  • (Tensor data, Tensor batch_sizes, tuple of Tensors hx, tuple of Tensors params, bool has_biases, int num_layers, float dropout, bool train, bool bidirectional)
    didn’t match because some of the arguments have invalid types: (Tensor, !tuple!, !list!, !bool!, !int!, !float!, !bool!, !int!, bool)
  • (Tensor input, tuple of Tensors hx, tuple of Tensors params, bool has_biases, int num_layers, float dropout, bool train, bool bidirectional, bool batch_first)
    didn’t match because some of the arguments have invalid types: (Tensor, !tuple!, !list!, bool, int, float, bool, !int!, bool)

My batch[0] data:

         [-269.,    0.,    0.,    0.,    0.,    0.,    0.,    0.]]])

Any idea on what I am doing wrong? I thought that it could be the way I am intializing my NN so I added the arguments name to the constructor but it doesnt seem to help.

Any suggestion is appreciated!

Kind regards

The bidirectional argument expect a bool value, while you are passing an int to it. Change it to bidirectional=False and it should work.
