OpenVINO Model Pass Python API

MatcherPass is used for pattern-based transformations. To create transformation you need:

1. Create a pattern
2. Implement a callback
3. Register the pattern and Matcher

In the next example we define transformation that searches for Relu layer and inserts after it another Relu layer.

.. doxygensnippet:: docs/snippets/ov_matcher_pass.py
   :language: py
   :fragment: [matcher_pass:ov_matcher_pass_py]

The next example shows MatcherPass-based transformation usage.

.. doxygensnippet:: docs/snippets/ov_matcher_pass.py
   :language: py
   :fragment: [matcher_pass_full_example:ov_matcher_pass_py]

After running this code you will see the next: text ``` model ops : parameter result relu

model ops : parameter result relu new_relu ```

In oder to run this script you need to export PYTHONPATH as the path to binary OpenVINO python models.
