Google Cloud AI Platform Optimizer API is completely broken when constructed using discovery.build("ml", "v1")

[Ark-kun]

Thanks for stopping by to let us know something could be better!

If you are still having issues, please be sure to include as much information as possible:

Environment details

• OS type and version: Linux
• google-api-python-client version: pip show google-api-python-client

Code example

from googleapiclient import discovery
ml_v1 = discovery.build("ml", "v1")
ml_v1.projects().locations().studies().list(parent='projects/<my-project>/locations/us-central1').execute()

The main issue is that baseUrl is "https://ml.googleapis.com/" instead of "https://us-central1-ml.googleapis.com/".

The https://us-central1-ml.googleapis.com/$discovery/rest?version=v1 discovery doc has this problem as well.

Can you please fix this or send it to the relevant Google teams, so that they fix their discovery docs.

Hi @Ark-kun,

You can change the effective base URl with the api_endpoint client option.

https://cloud.google.com/ai-platform/prediction/docs/regional-endpoints#python

from google.api_core.client_options import ClientOptions
from googleapiclient import discovery

endpoint = 'https://REGION-ml.googleapis.com'
client_options = ClientOptions(api_endpoint=endpoint)
ml = discovery.build('ml', 'v1', client_options=client_options)

@vinnysenthil Do the Vertex AI folks also cover this API? Is this a problem you're familiar with? It seems odd to me that a method doesn't work with the global endpoint.
