-***Special Note**: pad_type (asymmetric padding) does not support the cuDNN acceleration now, [explanations](https://github.com/foss-for-synopsys-dwc-arc-processors/synopsys-caffe/commit/b193bc72180a295ea9322837a9735cd72a552f7e#comments); To use it, you must turn off the cuDNN acceleration switch in *Makefile.config* for building.
