From the second time, just run the last line.
NOTE: Please understand this package may undergo severe backward-incompatible changes. This is a package I use for (1) my own research and (2) education (see, e.g., SNU_AOclass).
For (1): I always include a proper "snapshot" of this package to the publication, so any backward incompatible changes won't affect the reproducibility of the published results.
For (2): Each semester, students will try to download/install the newest versions of other packages (especially ccdproc, photutils, etc). But these packages sometimes introduce "breaking changes" to their source codes, and thus, I have to modify my codes to "work" with the newest versions of such packages (e.g., as of 2022 Apr, I suddenly had to drop photutils <= 1.3 due to its internal API change in version 1.4 & as of 2022 Dec, I also suddenly had to drop photutils <= 1.6 due to the same reason). Thus, backward incompatible changes are inevitable for me.
My justification is that this is not an "officially recommended" package by, e.g., STScI, but rather it is just a personal toolbox. Even for the name of this package, I tried not to occupy "photutilpy", which must be used by better-organized ones (such as photutils).
Enjoy astronomical data reduction!
