        Creates a glossary and returns the long-running operation. Returns
        NOT\_FOUND, if the project doesn't exist.

            >>> client = translate_v3beta1.TranslationServiceClient()

        Args:
            parent (str): Required. The project name.
            glossary (Union[dict, ~google.cloud.translate_v3beta1.types.Glossary]): Required. The glossary to create.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.translate_v3beta1.types.Glossary`
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will not
                be retried.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.
            metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
                that is provided to the method.

        Returns:
            A :class:`~google.cloud.translate_v3beta1.types._OperationFuture` instance.

        Raises:
            google.api_core.exceptions.GoogleAPICallError: If the request
                    failed for any reason.
            google.api_core.exceptions.RetryError: If the request failed due
                    to a retryable error and retry attempts failed.
            ValueError: If the parameters are invalid.
