tf.contrib.distributions.QuantizedDistribution.log_prob(value, name='log_prob')
Log probability density/mass function (depending on is_continuous).
Additional documentation from QuantizedDistribution:
For whole numbers y,
P[Y = y] := P[X <= lower_cutoff], if y == lower_cutoff,
:= P[X > upper_cutoff - 1], y == upper_cutoff,
:= 0, if j < lower_cutoff or y > upper_cutoff,
:= P[y - 1 < X <= y], all other y.
