From experience I think copy works already. But I think I don’t have a better answer for now than “try copy and if it doesn’t work, deepcopy” lol.

but now i start getting odd behaviour
ex
if one flow run first the name stick in the next call to
extract_flow_from_filei get the same object if i extract the flow that i change the name

Ah then I guess use deepcopy yep
Copy code
from prefect import Flow, task
from copy import copy
@task
def abc():
return 1
with Flow("test") as flow:
abc()
flow2 = copy(flow)
flow2.name = "test2"
print(flow.name)f
