Previously, the streaming op for computing PR curves had relied on the
tensor_summary
method to both produce a single update op to return aswell as add the update ops to various collections. That turned out
problematic since it wrote a duplicate summary, yielding an extra PR
curve plot in TensorBoard.
We now use a
tf.group
op and manually add individual update ops toeach collection.
Fixes #965.
