Validating a compiled Kubeflow Pipeline with Argo v2.7+ fails

[alexlatchford]

What steps did you take:

Since KFP upgraded to Argo==2.7, looks like the validation of compiled pipelines no longer works, see this line

Running argo lint /dev/stdin '' will always fail now whereas looks like that was used as a check in argo ~2.4.

What happened:

It errors when trying to validate a workflow.

What did you expect to happen:

I expected it to validate the workflow.

Environment:

KFP SDK version: v1.0.4 (actually a version of master from a few weeks back).

Anything else you would like to add:

Ideally it'd be great to be able to disable validation via the compile API/CLI. For now I've just removed argo from the PATH but obviously not ideal.

Due to the lack of offline support for workflow validation in argo clients > 2.4.3, you still need to use the 2.4 client to validate workflows offline, and it will not be updated atm in sdk. See this closed issue for more information: #4804
