4 months ago Hi! Thanks for the detailed report, I had not been able to look at it until now. It's been fixed and now it should be compatible with gala 1.8 (and backwards compatible with gala <1.4). Cheers!
Hello,
I'm having an issue querying streams using the following commands
import galstreamsmws = galstreams.MWStreams(verbose=True)Here is the error

My gala version: 1.7.1 (I may fix this by downgrading my gala version, but if this is an easy fix, then I don't have to do that) Thanks.
