def slice_output_shape(self, input_shape): shape = [input_shape[0], 1, 1] return tuple(shape)

The `slice_output_shape` function takes an input shape as a parameter and returns a new output shape.

In this case, the output shape is a tuple with three dimensions: the first dimension is the batch size, which is the same as the input shape. The second and third dimensions are both 1, which means that the output is a single scalar value for each element in the batch.

This function is likely used in a neural network model to reshape the output of a layer to match the expected input shape of the next layer.
