Hi,
I have three classes: Login, Input, Correction and when create pipeline object and add stages
m = pn.pipeline.Pipeline(debug=False)
m.add_stage(‘a’, Login())
m.add_stage(‘b’, Input(user=stage1.output()))
m.add_stage(‘c’, Correction(user=stage1.output()))
and then run
m.layout.servable()
i receive error message: ValueError: failed to validate GraphRenderer(id=‘1471’, …).selection_policy: expected an instance of type GraphHitTestPolicy, got None of type NoneType
I have installed panel 0.11.3.
Best regards,
Goran
