Contradiction in Doc for compute_target

compute_target
Union[xref:azureml.core.compute.DsvmCompute,azureml.core.compute.AmlCompute,azureml.core.compute.RemoteCompute,azureml.core.compute.HDInsightCompute,str,tuple]
[Required] The compute target to use. If unspecified, the target from the runconfig will be used. This parameter may be specified as a compute target object or the string name of a compute target on the workspace. Optionally if the compute target is not available at pipeline creation time, you may specify a tuple of ('compute target name', 'compute target type') to avoid fetching the compute target object (AmlCompute type is 'AmlCompute' and RemoteCompute type is 'VirtualMachine').

PROBLEM: It's a [Required] parameter. So how could there be a note like 'If unspecified, the target of the runconfig will be used....'.
I tested it, if you do not specify it it fails, even with a runconfig which has a compute_target defined.

error: executionId [453eac96]: Assignment for parameter Target is not specified

So the doc is incorrect here.

Revise AzureML-Docset/stable/docs-ref-autogen/azureml-pipeline-steps/azureml.pipeline.steps.PythonScriptStep.yml e a documentação vinculada de PythonScriptStep. Compare o requisito de compute_target com o comportamento relatado e atualize a descrição do parâmetro para que seu status de obrigatório e a redação do fallback sejam consistentes; a documentação não deve mais afirmar que há um fallback inutilizável.
