Worked in one State for 1st half of year, moved to 2nd State; where I did not earn any income (W-2 or 1099). Do I have to file in 2nd State?

I earned income in Louisiana for the first 5 months of the year. Move to Pennsylvania for school for the remaining 7 months, and did not earn any income (W-2, 1099) in PA. Do I have to file in PA? I already filed in LA.
