Thanks for a great tutorial! It helped me A LOT, when setting up my own DL rig. I just have one question, hope you can share your experience. I am using SSH tunneling to work in Jupyter notebooks in the browser on my Mac. But if the model takes long time to run and my Mac goes to sleep mode, the notebook freezes, and the results of model.fit are not updated. Do you always keep your Mac on when running big models, or you have some workaround for this?
