Write a custom object representation for a syrupy pytest

I need to write a custom object representation for a syrupy pytest. syrupy allows you to serialize built-in python types but I want to serialize a numpy ndarray type. To do this, you need to write a custom object representation as demonstrated here -> https://github.com/tophat/syrupy/blob/master/tests/examples/test_custom_object_repr.py Should be an easy job if you are competent in python and familiar with either syrupy or pytest.
