Astropy Conflict

[kaya4me2]

High-level problem description astropy version conflict

What did you do? Installing collected packages: PyYAML, pyerfa, astropy, photutils Attempting uninstall: astropy Found existing installation: astropy 3.2.3 Uninstalling astropy-3.2.3: Successfully uninstalled astropy-3.2.3 ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. sbpy 0.2.2 requires astropy<4.0,>=3.0, but you have astropy 5.0 which is incompatible. Successfully installed PyYAML-6.0 astropy-5.0 photutils-1.3.0 pyerfa-2.0.0.1 (sbpy) bash-3.2$

Hi @kaya4me2, thanks for the issue, but this report is a little bit unclear to me. Were you installing sbpy or upgrading astropy, or else what command brought you to this error?

[kaya4me2]

created new environment (condo create --name spy python 3.8), then pip installed sbpy , then attempted to get photutils into the environment as one of the user add-on, like ginga or pyradex

re:

The following packages will have to be installed manually, if the user wants to use them:

oorb: For orbit transformations (oo_transform) and propagations (oo_propagate), as well as ephemerides calculations (from_oo). pyradex: For non-LTE production rate calculation related to cometary activity (NonLTE). ginga and photutils: To interactively enhance images of comets with the CometaryEnhancement Ginga plugin.

Ah, I think this is a version conflict between sbpy 0.2.2 and photutils 1.3.0. Unfortunately, this means using an old version of photutils or using an advanced version of sbpy. If your goal is to use the Ginga plugin, it would be better to use an older photutils. Looking at photutils's history, it seems sbpy 0.2.2 and photutils<1.0 can work together. I tried it out in a virtual environment with success. For reference here is what I did:

python3 -m venv sbpy
source sbpy/bin/activate
pip install -U pip setuptools wheel
pip install sbpy
pip install 'photutils<1.0'
pip install ginga[gtk3] scipy

I'll close the issue for now, but re-open if you continue to have a problem. Also, look out for sbpy v0.3 when it is released as it should be compatible with contemporary astropy packages.
