Hi
I am running a workflow with inference workflows process-video on my local inference server.
I am trying to use the workflow block “velocity”, but I am continuously getting errors:
RuntimeError: Encountered the following errors while processing the video:
{
“error_type”: “ExecutionEngineRuntimeError”,
“error_message”: “Requested Workflow output serialization, but for output velocity which evaluates into Python
type: <class ‘supervision.detection.core.Detections’> cannot successfully apply any of registered serializers.”,
“error_context”: “inference_thread”
It is not clear, how to vizualize the outputs of velocity. I am trying to use label visualizalization, but the error remains. the documentation of this building block seems a bit “light”, but I would appreciate any hints on how to get that running. (both for visualizing and for sinking the data for later analysis)
thx & cheers
