  • param_node (bool) – Boolean indicating whether the node should be a ParamNode (True) or a Node (False).

  • args – Arguments to initialize an AbstractNode.

  • kwargs – Keyword arguments to initialize an AbstractNode.

Return type

Node or ParamNode

zeros#

  • param_node (bool) – Boolean indicating whether the node should be a ParamNode (True) or a Node (False).

  • args – Arguments to initialize an AbstractNode.

  • kwargs – Keyword arguments to initialize an AbstractNode.

Return type

copy#

tensorkrowch.copy(shape, param_node=False, *args, **kwargs)[source]#

Returns Node or ParamNode with a copy tensor, that is, a tensor filled with zeros except in the diagonal (elements \(T_{i_1 \ldots i_n}\) with \(i_1 = \ldots = i_n\)), which is filled with ones.

Parameters
