* Fix#612, TfidfVectorizer handles empty matrices as an input
* Add more unit tests, better consistency of error messages
* Update tfidfvectorizer.cc
* better comment
* fix comments
* add unit test failure for an empty input {0, 1}
* Adding a custom op interface to the C API to remove shared library dependency.
* Remove old custom op test
* Rework how custom ops handle inputs/outputs to enable custom op output shape calculation in the compute method
* Add a nicer C++ API for custom ops and switch the tests to use it.
Currently, when using OrtEnableProfiling to enable profiling using the C API,
the profile output file is created but is always empty.
The reason is that InferenceSession::EndProfiling() needs to be called to
write the profiling data to the output file.
However there's currently no way to call this function via the C API.
This adds a call to EndProfiling() to the descructor of the session if
profiling is enabled in the session options.
Generalize node removal method in graph_utils. This is a higher-level method that keeps the graph consistent so that no Resolve is needed after the removal of a node.
The new method supports the removal of nodes with a single input (be it an incoming node or an initializer) and a single output (but allowing multiple output edges of that output). It also takes into account the case that one of the output edges is fed to a subgraph.
Also updated the rewrite rules to use this new, less restrictive method, and improved the rules' conditions. Introduced a GraphEdge struct to simplify various methods in graph_utils.
* Update NMS to compatible with both TF & Pytoch models
