The operators that will be enhanced are the following:

  * missing transA and transB attributes.
  * cannot support bias of shape [1, outChannels].
• Sum: can no longer use Add operator because the latter can no longer support more than 2 inputs.

Modified files

• FCImpl.hpp, FCImpl.cpp, FCImpl_kernels.hpp and Test_FCImpl.cpp, add the attrs alpha, beta, transA and transB and support bias of shape [1, outChannels];
• SumImpl.hpp, SumImpl.cpp, SumImpl_kernels.hpp and Test_SumImpl.cpp, add Sum operator;

TODO

• Add alpha and beta attr to FC operator
• Add transA and transB attr to FC oprator
• Support bias of shape [1, outChannels] in FC oprator
• Add Sum operator
