10/18/2020, 11:40 PMHi, If I have two tasks in a flow that have no interdependency, how do I make them run concurrently?
For instance, this seems to cause task2 to wait until task1 finishes although task2 isn't dependent on task1.
Copy code
with Flow('') as flow
r=task1()
r2=task2()
task3(r)
flow.run()m
