Refactor requirements.txt

[andreped]

Instead of doing pip freeze > requirements.txt to get all requirements in a virtual environment, you probably want to make the requirements as minimalistic as possible.

Normally, I set the dependencies myself. For instance, tensorflow likely covers half of the requirements and then you only need to write tensorflow-gpu==1.13.1.

However, there are alternatives to pip freeze. I remember reading about pipreqs once. Have not tried it yet, but perhaps you could?
