PhD students in ML, how many hours on average do you work? [D]

I generally work around 9-10 hours a day, but not contiguously. I can usually carve out a dedicated chunk of time in the morning, take lab or project meetings in the afternoon, and block out around 6-8 PM for commute, exercise, socializing, and dinner. I also get work done in the evening, since my focus is often best then. On weekends, I mostly run errands and try out new food spots, but I also make sure to do at least a little bit of work every day. I try to schedule my Slurm jobs so they run when I’m not actively working, so I can collect results when I get back.
