`tf.train.confusion_matrix`.
    *   Add `tf.dtypes.` endpoint for every constant in dtypes.py. Moving
        endpoints in versions.py to corresponding endpoints in `tf.sysconfig.`
        and `tf.version.`. Moving all constants under `tf.saved_model`
        submodules to `tf.saved_model` module. New endpoints are added in V1 and

Class <org.gradle.api.internal.tasks.compile.incremental.compilerapi.constants.ConstantToDependentsMapping> is not annotated (directly or via its package) with @org.gradle.api.NonNullApi in (ConstantToDependentsMapping.java:0)

For example:

```python
c = tf.constant([[1,2,3,4], [-1,-2,-3,-4], [5,6,7,8]])

# Select two rows, one segment.
tf.sparse_segment_sum(c, tf.constant([0, 1]), tf.constant([0, 0]))
# => [[0 0 0 0]]

# Select two rows, two segment.
tf.sparse_segment_sum(c, tf.constant([0, 1]), tf.constant([0, 1]))
# => [[ 1  2  3  4]
#     [-1 -2 -3 -4]]
