Matlab 'neural net fitting' in google's tensorflow?

Hi there,

I use matlab's neural net fitting app to train a neural net using levinberg-marquardt training algorithm to predict a numeric output using 3 numeric inputs. I want to do this in python (google's tensorflow library) so that I can deploy this neural network on a website. Does anyone have a clue as to what the python version of matlab neural net fitting would be?

Thanks
