Rob,

had a look on the source of astrometry.net and agree. There is a mix of c and python and I have no clue how to separate this. So I'm with you and waiting the topics to be solved.
Many thanks for your work !

So I think I have a good idea now. I mightl go back to the way I had done this originally, with a series of buttons on a page in the startup wizard. The user can click them and install what is needed. I eventually abandoned this and embedded the minimal python installation that you saw previously because of issues and conflicts with different versions of python on different people's systems. It made it very hard to get the install scripts right. It proved for awhile to be easier to embed a python installation where I set everything up properly. But now that is broken since I cannot build an older version of python and embed it well without issues.But based on the work I was doing this weekend, I think I have some ideas on how to do a better job this time around.

Ok, I worked for many hours during the last couple of days on a better solution. I think I have it. I have set up an installer button and put it into the Astrometry configuration options for now. (I will see what others think about it, they might end up being moved somewhere else. But for right now, I would like to see if this new configuration and installer works. Please test this to make sure plate solving works correctly. Before you can use it, you MUST run the installer. There is no more embedded python. Please see my screenshot for details.

Please test plate solving with your system, to be even more helpful, you might want to try removing astropy, pyfits, numpy, python, and/or homebrew to see how the installers work. Let me know how it goes.

Thanks,

Rob

Thanks very much for all the hard work Rob. Unfortunately, as a software developer working with Python, installing Python3 via Homebrew is not a workable solution for me since it conflicts with Anaconda. However, I'll try to solve this myself. I guess it means fiddling around with the PYTHON_PATH and PATH variables and installing the required python dependencies via Anaconda.


Thanks, Wouter

That’s not a problem, it just means you can’t run the installers. You can configure another version of python to work with this. Just make sure that there is a python or a python link in /usr/local/bin or /usr/bin and that either pyfits or astropy modules are installed for that python.

The installers that I made are meant for the typical user who just has the system python installed and no packages.

Thanks for the confirmation of my suspicions, Rob!

Let me know if you think we need to make the path to python configurable for folks like you so that when astrometry is run, the path to python can be in the PATH. Also, would you need the PYTHONPATH environment variable set too?

Thanks for the offer, Rob. I'll investigate and will try to make it work. As soon as I have, I'll let you know. It may take a while though since I'll be off until Monday.

I installed the 3.2.3 Test
My index file location had to be set in the Astrometry.cfg setup and after fixing a file permission error on ~/./Library/Application\ Support/Astrometry everything worked.

When doing Python Setup my system only had to install astropy.

Using the simulator, both solving and load and solve worked.

Thanks!

So, I gave it a go as well because despite my earlier fear it turned out that I already had python3 installed via Homebrew. So I, too, only needed to install astrometry. Once done everything worked as Jerry described. Many thanks Rob!

Thank you for the test version of ksatrs. Unfortunately, the update did not solve the problem for me.

I ran into a problem running the python setup: it verified that home-brew was installed and attempted to instal python. After a short time, it put up a dialog saying: “Python installation failure”.

I opened a terminal window and attempted the installation per your instructions elsewhere in this thread. Home-brew claimed python was installed and up to date. I checked:

Robert-Lucass-Mac-Mini:~ rnlucas$ which python
/usr/bin/python
Robert-Lucass-Mac-Mini:~ rnlucas$ which python3
/usr/local/bin/python3
Robert-Lucass-Mac-Mini:~ rnlucas$ python3 -V
Python 3.7.3

After this, I retried the setup, and this time it appeared to complete normally.

Robert-Lucass-Mac-Mini:~ rnlucas$ pip install astropy
Requirement already satisfied: astropy in /usr/local/lib/python3.7/site-packages (3.2.1)
Requirement already satisfied: numpy>=1.13 in /usr/local/lib/python3.7/site-packages (from astropy) (1.16.4)


However, it still seems to fail in the same way (from Ekos):

Ideas?
