pyhgf.typing.vectorised.stack_layers(layers)

Combine N identical Layer instances into a single LayerStack.

All Layer``s must share static-field values (kind, coupling_fn, add_constant_input, has_volatility_parent, fully_connected) and have ``weights_mean of identical shape. Static fields are taken from the first layer; arrays are stacked along a new axis 0.

A LayerStack carries no DAG topology, so the continuous-layer fields (value_child_idx, volatility_child_idx, volatility_weights) have no counterpart here and continuous layers cannot be stacked.

Parameters:

layers (list) – The list of identical Layer instances to stack.

Returns:

The combined LayerStack.

Return type:

layer_stack
