astropy: Error building executable using pyinstaller

Building executables which include astropy seem to have a history of issues (e.g. https://github.com/astropy/astropy/pull/960#issuecomment-355678708). Initially I was getting an, ImportError: Astropy requires the 'six' module of minimum version 1.10, which I solved by using a trick given in the above PR:

I was able to get this to work using PyInstaller with the following pyinstaller options --exclude-module astropy and --add-data path_to/astropy:astropy – @fridgerator

Now I get the new error:

Traceback (most recent call last):

I’m using a virtualenv named vetest in the directory ve_test, trying to run with the command: pyinstaller -F pyapi.py --exclude-module astropy --add-data /Users/lzkelley/Programs/cosmo/ve_test/vetest/lib/python3.5/site-packages/astropy:astropy

The full output from pyinstaller is attached.

out.txt

An additional issue is that the resulting executable is >200MB, is that normal? The application I’m trying to package is really just using the astropy.cosmology.LambdaCDM class. Might there be a better way to include that alone?

yes, works!

I don’t have a solution, but a potential workaround which worked for me was the following: In the *.spec file, add:

import astropy
astropy_path, = astropy.__path__

Then in the Analysis, add (astropy_path, 'astropy') into the datas list and 'astropy' in the excludes list.

Hope this helps.

@lzkelley - the developer version of Astropy now only supports Python 3

I just tried running:

pyinstaller -F app.py

with the latest astropy, and the six issue is gone but this is still a problem:

Traceback (most recent call last):

(this error was discussed extensively in #960)

But it might work fine if doing: https://github.com/maartenbreddels/frozen_astropy

It’d be nice in the long run to not require that and have it work ‘out of the box’. For that to work, I think someone needs to go through the changes in #960 and apply the ones that are still relevant.

@burhankhanlodhy thanks this worked for me.

@astrofrog Shouldn’t it be possible to add this to the PyInstaller hook? Otherwise this hook would somehow miss its intended purpose.

Thanks @lamourj for the workaround. I had also to add the astropy dependencies as hiddenimports explicitly though:

# Integrate astropy as data directory instead of module:
import astropy
astropy_path, = astropy.__path__
datas=[(astropy_path, 'astropy')]
excludes=['astropy']
hiddenimports=['shelve', 'csv']    # Required by astropy
