Any improved support for GPU and Kubeflow?

Hey @Rohan, unfortunately the Kubeflow upstream project still doesn’t support Kuberentes 1.22 or higher, we are actively working with them to support these versions but this will probably not happen until 1.6. This is why the Kubeflow addon on microk8s keeps being disbaled on the latest releases. What we recommend users to do is using the 1.21/stable channel of microk8s and installing it following this documentation
