Backpropagation
========================

.. warning::

    Where possible, ``pysiglib.torch_api`` should be used rather than explicitly calling
    backpropagation functions. Explicit backpropagation can introduce subtle errors if called
    incorrectly. In addition, some ``pysiglib`` functions can only be backpropagated through
    using their ``pysiglib.torch_api`` variants and do not expose explicit backpropagation functions.
