torch.lgamma# torch.lgamma(input, *, out=None) → Tensor# Computes the natural logarithm of the absolute value of the gamma function on input. outi=ln∣Γ(inputi)∣\text{out}_{i} = \ln |\Gamma(\text{input}_{i})| outi=ln∣Γ(inputi)∣ Parameters input (Tensor) – the input tensor. Keyword Arguments out (Tensor, optional) – the output tensor. Example: >>> a = torch.arange(0.5, 2, 0.5) >>> torch.lgamma(a) tensor([ 0.5724, 0.0000, -0.1208])
