def Capabilities(self, request, context):
context.set_code(grpc.StatusCode.UNIMPLEMENTED)<EOL>context.set_details('<STR_LIT>')<EOL>raise NotImplementedError('<STR_LIT>')<EOL>
Capabilities allows the client to retrieve the set of capabilities that
        is supported by the target. This allows the target to validate the
        service version that is implemented and retrieve the set of models that
        the target supports. The models can then be specified in subsequent RPCs
        to restrict the set of data that is utilized.
