Currently this works when data layout is larger than 4 dimension. For 4D data, inline padding has conflict with vectorization introduced by that PR and will cause LLVM error.\r\n\r\nReproduce: apply vectorization function to 4D case and create a nnvm graph with a pooling operator with non-zero padding.\r\n\r\nTrack this problem in this issue.\r\n"}}
