lgamma¶

paddle. lgamma ( x, name=None ) [source]

Lgamma Operator.

This operator performs elementwise lgamma for input $X$. \(out = log\Gamma(x)\)

Parameters

• x (Tensor) – (Tensor), The input tensor of lgamma op.

• with_quant_attr (BOOLEAN) – Whether the operator has attributes used by quantization.

• name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.

Returns

(Tensor), The output tensor of lgamma op.

Return type

out (Tensor)

Examples

import paddle

x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
out = paddle.lgamma(x)
print(out)
