Pickling_​Across_​Nodes

Pickling Across Nodes

Python objects can be pickled then sent as String output from a node to be read and later unpickled in another Python node.

Pickling of a custom class requires that the class be defined in an importable module. This is both highly recommended and straightforward to do. An alternative option is depicted in this workflow when that is simply not an option.
