Creating a Bidirectional LSTM

So I’m trying to create a bidirectional LSTM and I have this code

model.add(Bidirectional(LSTM(5, return_sequences=True), input_shape=X.shape[1]))

I keep getting the following error,

TypeError: ‘int’ object is not iterable

it is over the input_shape parameter, but I’m confused on how to fix it.

The shape of the input is (494021, 118)

The shape of the output is (494021, 5)
