.. _operation reference: Operation Reference =================== .. currentmodule:: nvidia.dali The data processing graph within a DALI :ref:`Pipeline ` is defined by calling operation functions. They accept and return instances of :class:`~nvidia.dali.pipeline.DataNode`, which are *symbolic* representations of batches of Tensors. The operation functions cannot be used to process data directly. The constraints for defining the processing pipeline can be found in :ref:`this section ` of Pipeline documentation. The following table lists all operations available in DALI: .. include:: operations/fn_table .. include:: operations/fn_autodoc
