back to 1.0 of flytekit yeah

Rahul Mehta
04/10/2023, 10:26 PMFantastic, thanks for confirming @Yee
Rahul Mehta
04/12/2023, 3:38 PMHmm, it unfortunately looks like there were some incompatibilities between the 1.3.0 chart & flytekit 1.2.7 (we were unable to run any dynamic steps that fanned out/those tasks just stalled)

those should definitely be compatible.
Yee
04/12/2023, 4:32 PM
why can’t you upgrade flyte btw? what are the dependency issues you’re seeing?

Rahul Mehta
04/12/2023, 4:32 PMWe're unfortunately blocked on protobuf due to another dependency (hilariously enough, kubeflow pipelines)

Yee
04/12/2023, 4:32 PM
can you pull the futures file for the stalled tasks?
r
Rahul Mehta
04/12/2023, 4:32 PMRipping kubeflow out of our codebase soon, but right now the dependency constraints on protobuf aren't compatble
y
Yee
04/12/2023, 4:33 PM
so protobuf 3

Rahul Mehta
04/12/2023, 4:33 PMWhat's the futures file? Happy to look for it
y
Yee
04/12/2023, 4:33 PM
yeah
Yee
04/12/2023, 4:33 PM
well maybe just look at the admin endpoint, that might be easier.
r
Rahul Mehta
04/12/2023, 4:44 PMSorry, could you clarify? What should I be looking at?

04/14/2023, 12:37 AMSo just saw some more interesting behavior - we also hit this after rolling back, but in this particular situation we had 3 concurrently running dynamic workflows (that in turn all had >500 nodes in the pipeline). it took approx. an hour for the actual dynamic step to complete & fan-out, but all of them are now executing
