Current behavior?
The API documentation of tf.no_op specifies that tf.no_op() should return a TensorFlow Operation. The tests expect that calling tf.no_op() returns an instance of tf.Operation (and that its name property can be set by providing a name, e.g., "my_no_op"). The error message indicates that tf.no_op() is returning None rather than an Operation (None has no attribute "name"), causing the tests to fail. Given that the test suite is properly written according to the API's specification and the expected behavior, the issue stems from the source code implementation.
