Installation Issue with Ingress

[robyspace]

I encounter this error while setting up the seldon-core, as per this link, https://github.com/SeldonIO/seldon-core/blob/46ef14e60e1f8c5b4c30320b06293e8b60f721fa/notebooks/seldon_core_setup.ipynb

PS C:\WINDOWS\system32> helm install ambassador datawire/ambassador --set image.repository=docker.io/datawire/ambassador --set crds.keep=false --set enableAES=false --namespace seldon-system
Error: INSTALLATION FAILED: failed to install CRD crds/filter.yaml: resource mapping not found for name: "filters.getambassador.io" namespace: "" from "": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1beta1"

Pls help me rectify it.
