tf.keras.ops.lgamma

Computes the natural log of the absolute value of the Gamma function.

tf.keras.ops.lgamma(
    x
)

lgamma(x) = log(|Gamma(x)|)

Args
`x`	Input tensor.

Returns
A tensor with the same shape and floating-point dtype as `x`.

x = np.array([1.0, 2.0, 3.0, 4.0])
keras.ops.lgamma(x)
array([0.       , 0.       , 0.6931472, 1.7917595], dtype=float32)
