I am a bit lost. Why are you asking for clicking something on to start a deep learning environment?
As far as I know, PyTorch is a library. Thus, just like another python package, you import and use their function/modules in your python code.
If you are talking about docker environment, then this will be another topic.
If you are asking about using pre-trained model, then you probably can find tutorials how to load and use them.
Correct me if you are talking about different things.
