May I be nitpicky about lazy string formatting in logging? 😇

May I be nitpicky about lazy string formatting in logging? 😇

Thanks. It is better this way, so maybe I was just lazy.

I didn't do it because this message will usually be shown under normal circumstances anyway, so it doesn't help much to make them lazy. But the real reason is that I didn't want to look up how to covert the .3f from f-string to % syntax. Maybe I should have spent 0.1 seconds to try it.

There are still some more print statements to convert; I was just going through some notebooks and tried to clean up their output. Hence also #352 (the tqdm PR).
