no matches for kind "SeldonDeployment" in version "machinelearning.seldon.io/v1alpha2"

[vladislavkoz]

Describe the bug

I'm trying to apply deployment YAML on my KubeFlow(1.2) cluster.

After running: kubectl apply -f deployment.yaml I'm getting the following error:
error: unable to recognize "deployment.yaml": no matches for kind "SeldonDeployment" in version "machinelearning.seldon.io/v1alpha2"

Expected behaviour

Deployment created. The deployment.yaml file is ok.
I was using it with the previous KubeFlow versions deployed using kfctl + manifest

Environment

Kubeflow 1.2
1.18.12-gke.1210

This looks like Seldon Core is not installed and the CRD is not there. Are you sure you see the seldon-core-manager running in the kubeflow namespace?

[vladislavkoz]

@cliveseldon, You are right. I thought that it comes with the KubeFlow by default. I've tried to install it manually but faced another issue.
https://docs.seldon.io/projects/seldon-core/en/latest/workflow/install.html#install-seldon-core-with-helm

kubectl create namespace seldon-system

Now we can install Seldon Core in the seldon-system namespace.

helm install seldon-core seldon-core-operator
--repo https://storage.googleapis.com/seldon-charts
--set usageMetrics.enabled=true
--namespace seldon-system

helm install seldon-core seldon-core-operator
--repo https://storage.googleapis.com/seldon-charts
--set usageMetrics.enabled=true
--namespace seldon-system

@vladislavkoz I just ran the command locally and didn't seem to get any error, perhaps theree is already a CRD installed? Can you try upgrade helm CLI and remove all CRDs from Seldon and try again?

[ukclivecox]

Closing now. Please reopen if still an issue.

@cliveseldon if you try to use v3.5.* of helm you get the error.
