#### Code example

```python
import google.cloud.aiplatform as aip

PROJECT = "<my project>"
LOCATION = "europe-west1"
SERVICE_ACCOUNT = "<my SA>.iam.gserviceaccount.com"
NETWORK = "projects/<project id>/global/networks/<our network>"
IMAGE = "<some region>-docker.pkg.dev/<rest of docker image>"

aip.init(project=PROJECT, location=LOCATION)

job = aip.CustomContainerTrainingJob(
    display_name="custom-job-url-poc",
    container_uri=IMAGE,
    staging_bucket="gs://<some path>"
)

job.run(
    machine_type="e2-standard-4",
    service_account=SERVICE_ACCOUNT,
    network=NETWORK,
    sync=True,  # wait so the polling loop runs and logs the "View backing custom job:" URL
)

Output

Clicking https://console.cloud.google.com/ai/platform/locations/<region>/training/<id>?project=<project> redirects me to https://console.cloud.google.com/vertex-ai/locations/<region>/training/<id>?project=<project> which returns 404 since the announcement 2 days ago https://cloud.google.com/blog/products/ai-machine-learning/introducing-gemini-enterprise-agent-platform when Vertex AI was renamed to Gemini Enterprise Agent Platform, the url is no longer valid and redirects to https://console.cloud.google.com/agent-platform/locations/<region>/training/<id>?project=<project> instead, but apparently the infrastructure can't handle 2 levels of redirection, so it would be better to directly show user https://console.cloud.google.com/agent-platform/locations/<region>/training/<id>?project=<project> instead of https://console.cloud.google.com/ai/platform/locations/<region>/training/<id>?project=<project>.
