hey @daniel-fink!
thanks a lot for reporting - and welcome to the forum! feel free to Introduce yourself if youâd like.
this is unexpected behaviour as metrics shouldnât be throwing errors - may I ask what OS / environment youâre using as I havenât encountered this before?
either way, that attribute throwing the error isnât used by our metrics anymore so Iâve dropped it and released v2.7.1 of specklepy
which should resolve this issue for you! let me know if you run into any other issues getting started.
