You might want to try installing anaconda[0]. After you have installed, follow the instructions here[1]. There are also lots of videos in youtube if you have not yet done a little bit of googling. By the way, this all requires that you know how to code in python else you can get your hands wet here[2].

Now if you already know how to code in python and know how to use jupyter, you're ready to learn about neural networks. This book[3] did a really good job in explaining the subject.

And, this is what jupyter notebook can do[4].
