[英]StatusCode.UNIMPLEMENTED when making Vertex AI API call
我有一個簡單的 Python 應用程序調用 Vertex AI API,它在運行時失敗,我不明白為什么。 應用如下:
from google.cloud import aiplatform_v1
def sample_list_datasets():
client = aiplatform_v1.DatasetServiceClient()
request = aiplatform_v1.ListDatasetsRequest(
parent="projects/MYPROJECT/locations/us-central1",
)
page_result = client.list_datasets(request=request)
for response in page_result:
print(response)
sample_list_datasets()
運行時,它失敗並顯示:
E0126 03:52:04.146970105 22462 hpack_parser.cc:1218] Error parsing metadata: error=invalid value key=content-type value=text/html; charset=UTF-8

The above exception was the direct cause of the following exception:

google.api_core.exceptions.MethodNotImplemented: 501 Received http2 header with status: 404
我可能做錯了什么?
將代碼更改為以下內容使其工作:
from google.cloud import aiplatform_v1
from google.api_core.client_options import ClientOptions
def sample_list_datasets():
service_base_path='aiplatform.googleapis.com'
region='us-central1'
client_options = ClientOptions(api_endpoint=f"{region}-{service_base_path}")
client = aiplatform_v1.DatasetServiceClient(client_options=client_options)
request = aiplatform_v1.ListDatasetsRequest(
parent="projects/MYPROJECT/locations/us-central1",
)
# Make the request
page_result = client.list_datasets(request=request)
# Handle the response
for response in page_result:
print(response)
sample_list_datasets()
在此處找到的 API 請求的文檔中暗示了該解決方案。 在那篇文章中有一個代碼示例,在代碼示例中有一些注釋,在注釋中寫了以下內容:
- 它可能需要在創建服務客戶端時指定區域端點,如下所示: https://googleapis.dev/python/google-api-core/latest/client_options.html
這是核心線索。 當我們進行 Vertex AI 調用時,我們必須指定將請求發送到哪里。 為此,我們將api_endpoint
選項設置為[REGION]-aiplatform.googleapis.com
