                1. The ``api_endpoint`` property can be used to override the
                default endpoint provided by the client when ``transport`` is
                not explicitly provided. Only if this property is not set and
                ``transport`` was not explicitly provided, the endpoint is
                determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment
                variable, which have one of the following values:
                "always" (always use the default mTLS endpoint), "never" (always

                default mTLS endpoint if client certificate is present; this is
                the default value).

                2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable
                is "true", then the ``client_cert_source`` property can be used
                to provide a client certificate for mTLS transport. If
                not provided, the default SSL client certificate will be used if
                present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not
                set, no client certificate will be used.

                3. The ``universe_domain`` property can be used to override the
                default "googleapis.com" universe. Note that ``api_endpoint``
                property still takes precedence; and ``universe_domain`` is

                print(response)

        Args:
            request (Optional[Union[google.cloud.aiplatform_v1beta1.types.RawPredictRequest, dict]]):
                The request object. Request message for
                [PredictionService.RawPredict][google.cloud.aiplatform.v1beta1.PredictionService.RawPredict].
            endpoint (:class:`str`):
                Required. The name of the Endpoint requested to serve
                the prediction. Format:
                ``projects/{project}/locations/{location}/endpoints/{endpoint}``

                This corresponds to the ``endpoint`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            http_body (:class:`google.api.httpbody_pb2.HttpBody`):
                The prediction input. Supports HTTP headers and
                arbitrary data payload.

                A
                [DeployedModel][google.cloud.aiplatform.v1beta1.DeployedModel]
                may have an upper limit on the number of instances it
                supports per request. When this limit it is exceeded for
                an AutoML model, the
                [RawPredict][google.cloud.aiplatform.v1beta1.PredictionService.RawPredict]
                method returns an error. When this limit is exceeded for
                a custom-trained model, the behavior varies depending on
                the model.

                You can specify the schema for each instance in the
                [predict_schemata.instance_schema_uri][google.cloud.aiplatform.v1beta1.PredictSchemata.instance_schema_uri]
                field when you create a
                [Model][google.cloud.aiplatform.v1beta1.Model]. This
                schema applies when you deploy the ``Model`` as a
                ``DeployedModel`` to an
                [Endpoint][google.cloud.aiplatform.v1beta1.Endpoint] and
                use the ``RawPredict`` method.

                This corresponds to the ``http_body`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            retry (google.api_core.retry_async.AsyncRetry): Designation of what errors, if any,
                should be retried.
            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, str]]): Strings which should be
                sent along with the request as metadata.

        Returns:
            google.api.httpbody_pb2.HttpBody:
                Message that represents an arbitrary HTTP body. It should only be used for
                   payload formats that can't be represented as JSON,
                   such as raw binary or an HTML page.

                   This message can be used both in streaming and
                   non-streaming API methods in the request as well as
                   the response.

                   It can be used as a top-level request field, which is
                   convenient if one wants to extract parameters from
                   either the URL or HTTP template into the request
                   fields and also want access to the raw HTTP body.

                   Example:

                      message GetResourceRequest {
                         // A unique request id. string request_id = 1;

                         // The raw HTTP body is bound to this field.
                         google.api.HttpBody http_body = 2;

                      }

                      service ResourceService {
                         rpc GetResource(GetResourceRequest)
                            returns (google.api.HttpBody);

                         rpc UpdateResource(google.api.HttpBody)
                            returns (google.protobuf.Empty);

                      }

                   Example with streaming methods:

                      service CaldavService {
                         rpc GetCalendar(stream google.api.HttpBody)
                            returns (stream google.api.HttpBody);

                         rpc UpdateCalendar(stream google.api.HttpBody)
                            returns (stream google.api.HttpBody);

                      }

                   Use of this type only changes how the request and
                   response bodies are handled, all other features will
                   continue to work unchanged.

                Message that represents an arbitrary HTTP body. It should only be used for
                   payload formats that can't be represented as JSON,
                   such as raw binary or an HTML page.

                   This message can be used both in streaming and
                   non-streaming API methods in the request as well as
                   the response.

                   It can be used as a top-level request field, which is
                   convenient if one wants to extract parameters from
                   either the URL or HTTP template into the request
                   fields and also want access to the raw HTTP body.

                   Example:

                      message GetResourceRequest {
                         // A unique request id. string request_id = 1;

                         // The raw HTTP body is bound to this field.
                         google.api.HttpBody http_body = 2;

                      }

                      service ResourceService {
                         rpc GetResource(GetResourceRequest)
                            returns (google.api.HttpBody);

                            returns (google.protobuf.Empty);

                      }

                   Example with streaming methods:

                      service CaldavService {
                         rpc GetCalendar(stream google.api.HttpBody)
                            returns (stream google.api.HttpBody);

                         rpc UpdateCalendar(stream google.api.HttpBody)
                            returns (stream google.api.HttpBody);

                      }

                   Use of this type only changes how the request and
                   response bodies are handled, all other features will
                   continue to work unchanged.
