Extend and Test the Op in Python
Once you have built your custom op shared library, you can follow the example in tensorflow_zero_out/python/ops, and instructions here...

The original link is to https://www.tensorflow.org/extend/adding_an_op#use_the_op_in_python, which is now missing.
It should now probably link to https://www.tensorflow.org/guide/create_op#use_the_op_in_python.
