Hi, all

I faced the below error on converting NASNetMobile by Keras application for DV.

I pushed a branch to fix parts of issue.

There is one issue remain: The model uses Cropping2D layers, which is not supported by HW. It seems use the ZeroPadding and Cropping to ship pooling results and then concatenate those results. Since it is ignored by now, The converted network will be less precise.
