Aboud Sigmoid in Pytorch

I was checking some Pytorch doccumentation, and I found these ones about Sigmoid:

can somebody give me some guiadance about the difference or similiarities of these two piece of Pytorch Docs?

Best regards

Hi, they are the same sigmoid function (with the same formula if you checked), but the 1. is in pytorch functional api - you know you can define network models in pytorch in standard sequential way or functional way. (actually these 2 ways are also there in all other frameworks, so not pytorch specific)

thanks very much @AmorfEvo
