'GreatCircleICRSFrame' object has no attribute '_R'

[martinmestre]

Hi all,
thanks developing the Gala package!
I made a new installation of Gala with pip (stable and dev) and in both situations I have the same error:
ERROR: Python: AttributeError: 'GreatCircleICRSFrame' object has no attribute '_R'
The error starts when calling reflex_correct and using a Galstreams frame.
I am calling Gala from Julia so the error might come from my side.
Thank you very much!

Hey @martinmestre! What version of galstreams are you using? I remember an error like this, but I fixed some issues with the way galstreams was using GreatCircleICRSFrame - I'm not sure if those fixes made it into a released version. What if you try installing the dev version of galstreams? Do you have a minimum working example of getting the error using reflex_correct?

Hi @adrn,
thanks for your answer.
I prepared a MWE in Python and the problem was reproduced.
I am using

python 3.10.15
galstreams  1.0.2.dev294
gala 1.9.2.dev5 

I prepared a notebook with an "almost MWE" (The data is from GD-1-PB18 at the CATS repository).
As I am not able to attach a notebook here, I have uploaded it to public repo I develop:
https://github.com/martinmestre/IntrospectiveStreams.jl/blob/main/test/gala_reflex_correct.ipynb
By the end of the notebook it is possible to see which is the line inside reflex_correct that causes the problem.
Please let me know if I am missing something :)
Thanks!
All the best!
