even harder question what are the pros and cons of pi torch versus tensorflow i see okay you can go with no comment so a disclaimer to this is that the last time i used tensorflow was probably like four years ago and so it was right when it had come out uh because so i started on like deep learning in 2014 or so and the dominant sort of parent fram...
