This MR add NHWC support to
Concatoperator, andPadoperator created byConv.Original behaviour
Concat
Concat didn't support NHWC format, so tensors must be transposed back to NCHW before concat, and may be converted to NHWC to do other compuation.
Pad of Conv
When explicit padding is used in Conv, the pad was done before input tensor was transposed, which also leads to a pair of unresolvable
Transposeoperators.Changes
This MR added NHWC support to
concatoperator, and pad was done on transposed input of conv.
