Import internal data structure created by Debug Export. Can only read files exported in this Sympathy version.




Documentation
:::::::::::::

This is not a regular import node. The files to be imported must be created
by :ref:`org.sysess.sympathy.debug.export` on the same Sympathy version. If
you just want to read normal exported sydata files you should use
:ref:`Table`, :ref:`ADAF` etc.

On the other hand this node is able to import any data type from a sydata
file, which can be useful for debugging purposes.

.. warning::
    This node **is not secure**. Only import data files you trust.

    Some of Sympathy's data types (e.g. :ref:`Figure<figure_type>` and
    :ref:`Model<model_type>`) are based on Python's pickle protocol, and as
    a result they can trigger execution of arbitrary code when imported.
