I'm new to machine learning and been learning SciKit Learn and really love it. It is amazingly easy and allows really quick results for someone with no experience. My friend says it is all deep learning and neural networks. How hard is the transition to tensorflow, theano and less if I only know SciKit Learn and about 6-7 algorithms. I understand kfolds, CV and gridsearch. Outside of the simplicity and speed is there any reason to continue learning SciKit Learn and how much will carry over to neural networks and deep learning?
