``Inferencer2`` is a module for running offline model inference, preprocessing and postprocessing based on cnis(Cambricon Neuware Infer Server, hereinafter referred to as ``Infer Server``). ``Infer Server`` provides offline model loading and management, inference tasks scheduling and etc. functions. ``Infer Server`` greatly simplifies the development and deployment of deep learning applications for the ``MLU``(Machine Learning Unit) platform, as well as is very efficient, therefore we recommend users to use ``Inferencer2`` which is based on ``Infer Server``. Also users could create customized module based on ``Infer server`` , and ``Inferencer2`` is a sample for you.
