What are the libraries for building an ANN in Python?

Question

Python

Good afternoon!
Please tell me the libraries for building networks in python. I know there is Pytorch. I can't figure out the tutorial in English. Is it possible to implement the Levenberg-Marquadt algorithm in this library? I have experience in building LM networks in Matlab. There is a lot of information in RuNet on explaining the principle of networks in python. Simple networks, sigmoid function, etc. Everything seems to be clear, but now the task is to build a regression model and I want to use ready-made libraries to solve this problem.
Thank you!

Tensorflow from Google. There's a lot of little goodies in there; seq2seq with attention and beam search on it, for example, is pretty easy to file.
Keras - was previously an abstraction layer over Theano and Tensorflow, but Theano ordered a long life, and Keras joined TF. Allows you to do simple things faster.
There is also MXNet from Apache.
