Computes the log of the absolute value of Gamma(x) element-wise.
tf.math.lgamma(
x, name=None
)
For positive numbers, this function computes log((input - 1)!) for every element in the tensor.
lgamma(5) = log((5-1)!) = log(4!) = log(24) = 3.1780539
Example:
x = tf.constant([0, 0.5, 1, 4.5, -4, -5.6])
tf.math.lgamma(x) ==> [inf, 0.5723649, 0., 2.4537368, inf, -4.6477685]
