Methods
public boolean containsWebAccessUris(String key)
Output only. URIs for accessing interactive
shells
(one URI for each training node). Only available if this trial is part of
a
HyperparameterTuningJob
and the job's
trial_job_spec.enable_web_access
field is true.
The keys are names of each node used for the trial; for example,
workerpool0-0 for the primary node, workerpool1-0 for the first node in
the second worker pool, and workerpool1-1 for the second node in the
second worker pool.
The values are the URIs for each node's interactive shell.

public boolean equals(Object obj)
Parameter
Returns
Overrides
public String getClientId()
Output only. The identifier of the client that originally requested this
Trial. Each client is identified by a unique client_id. When a client asks
for a suggestion, Vertex AI Vizier will assign it a Trial. The client
should evaluate the Trial, complete it, and report back to Vertex AI
Vizier. If suggestion is asked again by same client_id before the Trial is
completed, the same Trial will be returned. Multiple clients with
different client_ids can ask for suggestions simultaneously, each of them
will get their own Trial.
string client_id = 9 [(.google.api.field_behavior) = OUTPUT_ONLY];
| Type | Description |
String | The clientId.

public ByteString getClientIdBytes()
Output only. The identifier of the client that originally requested this
Trial. Each client is identified by a unique client_id. When a client asks

Vizier. If suggestion is asked again by same client_id before the Trial is
completed, the same Trial will be returned. Multiple clients with
different client_ids can ask for suggestions simultaneously, each of them
will get their own Trial.
