尝试使用街景发布服务客户端Python更新照片元数据时出错

Question

我在街景中上传了几张照片，我想使用Python客户端库来更新它的元数据。下面是我的代码片段：

from google.proto.streetview.publish.v1 import resources_pb2
from google.streetview.publish.v1 import street_view_publish_service_client as client
from google.protobuf import field_mask_pb2

streetview_client = client.StreetViewPublishServiceClient(credentials=credentials)

for photo in streetview_client.list_photos(0, ''):
    con = resources_pb2.Connection()
    target_id = resources_pb2.PhotoId()
    target_id.id = "photo_id"
    con.target.id = target_id.id
    photo.connections.extend([con])
    update_mask = field_mask_pb2.FieldMask()
    update_mask.FromJsonString("connections")
    response = streetview_client.update_photo(photo, update_mask)
    break

我想连接这两张照片，所以我将目标id添加到查询照片中，并将字段“connections”添加到update\u mask中。 update_photo调用后的结果是以下错误消息：

google.gax.errors.RetryError: RetryError(Exception occurred in retry method that was not classified as transient, caused by <_Rendezvous of RPC that terminated with (StatusCode.INVALID_ARGUMENT, Empty level name is not accepted.)>)

有什么提示吗？你知道吗

为了在两张照片之间建立连接，需要使用^{}。Connections应该设置在Photo的正下方。另外，请注意需要实现的^{}的元数据。他说

下面是一个示例代码片段。他说

pose = resources_pb2.Pose(level=resources_pb2.Level(name="lvl", number=0))
connection1 = resources_pb2.Connection(target=resources_pb2.PhotoId(id="idOfConnection1"))
photo = resources_pb2.Photo(connections=[connection1], pose=pose)
