Hi all, I’ve been playing between prefect 2 and 3 and having tried something in 3, I then downgraded to 2 and am now getting an error when ever I try running prefect,

'copy_on_model_validation' has been removed

. Any ideas what I can do to get ride of this error?

Hi Pascal! I haven't seen this error before. Have you had any luck with creating separate virtual environments for your Prefect 2 and 3 installations?

Hi @Bianca Hoch, I did create virtual environments but it was a single one where I was just

pip install prefect>3

and

<3

when switching between the two and also setting for each a

PREFECT_HOME

for each. But I have now created completely separate environments along with each having their own home directories and I am no longer encountering this issue
