Review comment:
@zheng-da Now graph partitioning may change the order of inputs. This is a
basic requirement from graph optimization purpose. For example, if we found
there's a redundant op that doesn't contribute to graph output, shouldn't we
remove it? If the answer is yes, then the input list will be changed.
Besides, current API design provides bad support for inputs with same
name(if you treat the undocumented behavior is a kind of support). We should
fix this anyway.

Review comment:
Yeah, I understand that you can find the order from the code, but it's not
guaranteed, and you shouldn't make any assumption based on that, as it may
change in future because the order isn't a part of list_arguments() spec, at
least for now.
I guess we should answer this question first, which is, should we support
inputs with same name? If the answer is shouldn't, then we need to rename those
inputs with same name in unit test and add corresponding check and document to
disallow user using like that.
If the answer is we should, then we need to define a clear way for
distinguishing inputs apart from name on API level, instead of the undocumented
DFS order.
According to the current API design, I guess inputs with same name shouldn't
be supported, as the order of list_arguments() is unique only if inputs has
unique name. Adding DFS order to list_arguments() spec isn't user friendly, as
it's hard for end user to find out the final DFS order from a complex topology,
as single op(eg. rand_zipfian) from end-user level may be consist of many small
ops in final computing graph.

Review comment:
`If the input type is a list of NDArray, the order should be same as the
order of list_arguments().`
If there're inputs with same name, for your case then the list_arguments()
will be like,
['data', 'data', 'data' ...]
Then, how can we know which 'data' is the data2?

If the input type is a list of NDArray, the order should be same as the

In either case, all the arguments must be provided.**

Review comment:
@KellenSunderland Sorry for responding late. For mkldnn quantization flow,
we won't offline quantize any params, but using fp32 params(eg. weight and
bias) for quantized convolution. We will online quantize convolution params in
first forwarding. For the code here, it's for the default output format of
'quantize' op when using in mkldnn quantization flow, this won't effect
non-mkldnn quantization flow.

Review comment:
@reminisce Code style is not consistent in this file. SubgraphSelector use
different coding style with SubgraphProperty, which making me confusing which
coding style should to follow. For example, SubgraphSelector uses /*! */ style
comment with param description, and long parameter name(eg nnvm::Node
_node), while SubgraphProperty uses \\ style comment without param
description, and short parameter name(eg. const nnvm::Symbol ).
Changing these 2 SubgraphProperty functions into SubgraphSelector style
doesn't make sense to me. If you insist, I'd like to adjust the code style for
whole file.

Review comment:
@zheng-da If we don't need more than 1 subgraph in a node, why we define
subgraphs as a vector?
@reminisce If subgraph is produced and handled by each backend itself, then
each backend can decide its subgraph sequence. But the thing is, we need to add
code to common part to handle all subgraphs from various backends. This part
change is an example. So it's better to have such a rule that all backends to
follow, and then we can make check based on that.

Review comment:
This is to solve first layer calibration problem. If we try to quantize
first layer(eg. conv0), then we will insert an quantize op between data and
conv0. After enabling calib_quantize_op, we will collect calibration info on
data, which can't be done by set_monitor_callback as it only monitors op's
output, but data is not an output of any op. To solve this problem, we insert
an identity op for data, to convert it to identity's output, then we can use
set_monitor_callback to do calibration for it.

Review comment:
Also, I don't know which kind of CHECK can be added here.
CHECK(node->attrs.subgraphs.size() == 1)? Why can't we support more than 1
subgraph symbol? All we need to check here is the demanded symbol should be in
index 0, but this is not checkable.

Review comment:
OK. But this is not a good design that we didn't have a rule that which
index should be the subgraph symbol node as I comment in your subgraph PR. We
have to assume that the first node(index 0) is the subgraph node, and all
developers won't break this.

Review comment:
It's an abstraction to isolate mkldnn convolution params with fusion params:
MKLDNNConvFullParam defines in mkldnn_convolution-inl.h, which only contains
the options convolution needed, and will pass to
MKLDNNConvolutionForwardFullFeature.
MKLDNNConvFusionParam defines in mkldnn_conv-inl.h, which is used for
SgMKLDNNConvParamParser, and to support fusion related function in
SgMKLDNNConvOperator::Forward.

For mkldnn, yes. nhwc should be the default int8 layout, just like nchw for
fp32.

Actually, out_data always has same memory description with fwd->fwd_pd, so
we should use GetMKLDNNData instead of GetMKLDNNDataReorder. Then out_mem will
always be the memory in out_data.
