Pipelines End-to-end on GCP: fix example & update screenshots #1611

amygdala · 2020-02-07T15:11:07Z

https://www.kubeflow.org/docs/gke/pipelines/pipelines-tutorial/

got a reminder from someone (doing a hosted pipelines-related bug bash) that the screenshots here need to be updated. And maybe more tweaks? Let's check it during the docs sprint. I'll try to do it.

Thanks @amygdala!

@amygdala I've moved this issue to In progress in the doc sprint Kanban board, because the issue is assigned to you. Happy sprinting!

amygdala · 2020-02-10T20:20:30Z

This example no longer runs properly either; will look into it. Getting some kind of memory reference error related to ksonnet (!).
Also, the python pipeline spec. could use some syntax updates.

amygdala · 2020-02-10T20:47:51Z

hi @jinchihe , not sure if you're the right one to ping on this: when I tried running the example, I got the following ksonnet-related segfault error in the serve step.
I don't have visibility as to what's going on in the docker image that this step is using (gcr.io/ml-pipeline/ml-pipeline-kubeflow-deployer:7775692adf28d6f79098e76e839986c9ee55dd61)

Are you the right person to look into this? (I'm thinking it might be best to find a non-ksonnet implementation of this step.)

Update: I'll try this more recent component definition: https://github.com/kubeflow/pipelines/blob/master/components/kubeflow/deployer/component.yaml to see if that helps.

Update 2: using a newer image fixed the issue (kinda), so please ignore my earlier comment, @jinchihe. There are still some problems with this op, but I think the KFP team is the right group to ask.
(There's a problem with the serving step as well, but I think Dan S is the one to ping on that).

update 3: okay, this example seems completely broken ...

amygdala · 2020-02-11T02:02:37Z

amygdala · 2020-02-11T03:00:51Z

in addition to the probs with the serving step, the webapp step of the pipeline is getting a ksonnet-related seg fault.

joeliedtke · 2020-02-11T16:44:22Z

Chatted with @amygdala and @sarahmaddox: since this tutorial does not currently work, I will remove this tutorial from the site while it is being revised.

jtfogarty · 2020-04-07T02:00:04Z

/priority p2

renat-abbyazov · 2020-04-10T19:32:26Z

Had no experience with segfault error but got 'No Major.Minor.Patch elements found', fixed by adding --api-spec=version:v1.15.0 to all ks commands

ks init --api-spec=version:v1.15.0 tf-serving-app

after that had webserving app deployed successfully.

the example also can't support k8s with version >= v1.16.0, since its component ml-pipeline-kubeflow-deployer depends on ksonnect, and ksonnect can't support k8s with version >= v1.16.0:

v1.16.0/v1.7.0 with a lot memory consuming and 100%cpu, can't exit within a minute.
>=v1.18.0 reports the error 'No Major.Minor.Patch elements found' due to this k8s commit set version to unversioned in api/openapi-spec/swagger.json.
