Astropy
Installation instructions: https://docs.astropy.org/en/stable/install.html
Astropy required Python packages.
Astropy installation files archive with various ISA support. Download the appropriate wheel file, then install with the command pip3 install /home/pi/file_name.whl.
Astropy comes with the full Anaconda install. With Miniconda, the recommended way to install Astropy is using the command conda install astropy.
Astropy 0.3.0 is what Miniconda 3.5.5 installs. This is a much earlier version than I would have expected. Astropy 0.3 was released in Nov 2013.
Astropy 0.4 was released in Jul 2014. Therefore Astropy 0.3 was the latest version when Miniconda 3.5.5 was released and is probably why Miniconda 3.5.5 installs with Astropy 0.3.
Astropy v1.2 requires Python v2.7 or later and Numpy 1.7.0 or later.
Astropy v1.3: “vectors and coordinates can be reshaped like arrays.”
Astropy v2.0.0 started to implement Python 3 but specifically says does not change functionality with Python 2. However, from 2.0.0 to 2.0.18, Python 2 was gradually phased out.
Astropy v3.0 is the first version that supports only Python 3.
I think I want Astropy v1.3 – unless it won’t run for some reason. Why does Miniconda 3.5.5 install Astropy 0.3.0? Was it the current Astropy at the release time? Answer: yes, it was. Do the newer Astropy versions require newer ISA? At some point, I got a “need ARMv7” error so probably.
However, also unexpectedly, it updates Python from 2.7.7 to 2.7.8. Python 2.7.8 was released in Jul 2014.
