Apparently, there is no 32-bit Windows version of photutils

[JuanCab]

Installation instructions fail is someone is running 32-bit version of Anaconda. Easy to accidentally do. We should revise instructions to say to make sure to install 64-bit version of anaconda.

alternatively pip install photutils should work even on those systems

(We do test photutils on 32bit linux, but not on windows, so your suggestion of making sure 64bit conda is used is preferable though)

[JuanCab]

Yeah, I figured anyone using Windows 7 or 10 is almost certainly using a 64-bit version of those OSes on a computer less than 5 years old, so the 64-bit option is preferable. We had a workshop participant who installed the 32-bit version of Miniconda on a 64-bit Windows, and then had an issue with the environment not resolving because the 32-bit windows version of photutils is NOT in the astropy channel.

Conda-forge stopped support for 32-bit windows (conda-forge/staged-recipes#5640). The anaconda astropy channel simply mirrors conda-forge.

For 32-bit windows systems, one will need to install using pip (there's even a wheel for Win 32).

Maybe it would pedagogically make sense to suggest to pip install everything after conda creating the env? Transferable skill for the case when a package is not conda available.

In #186 we're now requesting participants to install a 64-bit version of Miniconda.

Thanks, @stargaser. I'm closing this issue now. If ever needed, there are 32-bit windows wheels available via pip.
