## Methods

### TpuClient

    TpuClient(
        *,
        credentials: typing.Optional[google.auth.credentials.Credentials] = None,
        transport: typing.Optional[
            typing.Union[
                str,
                google.cloud.tpu_v1.services.tpu.transports.base.TpuTransport,
                typing.Callable[
                    [...], google.cloud.tpu_v1.services.tpu.transports.base.TpuTransport
                ],
            ]
        ] = None,
        client_options: typing.Optional[
            typing.Union[google.api_core.client_options.ClientOptions, dict]
        ] = None,
        client_info: google.api_core.gapic_v1.client_info.ClientInfo = google.api_core.gapic_v1.client_info.ClientInfo
    )

Instantiates the tpu client.

| **Parameters** ||
|---|---|
| **Name** | **Description** |
| `credentials` | `Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment. |
| `transport` | `Optional[Union[str,TpuTransport,Callable[..., TpuTransport]]]` The transport to use, or a Callable that constructs and returns a new transport. If a Callable is given, it will be called with the same set of initialization arguments as used in the TpuTransport constructor. If set to None, a transport is chosen automatically. |
| `client_options` | `Optional[Union[google.api_core.client_options.ClientOptions, dict]]` Custom options for the client. 1. The `api_endpoint` property can be used to override the default endpoint provided by the client when `transport` is not explicitly provided. Only if this property is not set and `transport` was not explicitly provided, the endpoint is determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment variable, which have one of the following values: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto-switch to the default mTLS endpoint if client certificate is present; this is the default value). 2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide a client certificate for mTLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used. 3. The `universe_domain` property can be used to override the default "googleapis.com" universe. Note that the `api_endpoint` property still takes precedence; and `universe_domain` is currently not supported for mTLS. |
| `client_info` | `google.api_core.gapic_v1.client_info.ClientInfo` The client info used to send a user-agent string along with API requests. If `None`, then default info will be used. Generally, you only need to set this if you're developing your own client library. |

| **Exceptions** ||
|---|---|
| **Type** | **Description** |
| `google.auth.exceptions.MutualTLSChannelError` | If mutual TLS transport creation failed for any reason. |

### __exit__

    __exit__(type, value, traceback)

Releases underlying transport's resources.

> [!WARNING]
> **Warning:** ONLY use as a context manager if the transport is NOT shared with other clients! Exiting the with block will CLOSE the transport and may cause errors in other clients!

### accelerator_type_path

    accelerator_type_path(project: str, location: str, accelerator_type: str) -> str

Returns a fully-qualified accelerator_type string.

### cancel_operation

    cancel_operation(
        request: typing.Optional[
            typing.Union[google.longrunning.operations_pb2.CancelOperationRequest, dict]
        ] = None,
        *,

        metadata: typing.Sequence[typing.Tuple[str, typing.Union[str, bytes]]] = ()
    ) -> None

Starts asynchronous cancellation on a long-running operation.

The server makes a best effort to cancel the operation, but success
is not guaranteed. If the server doesn't support this method, it returns
`google.rpc.Code.UNIMPLEMENTED`.

| **Parameters** ||
|---|---|
| **Name** | **Description** |
| `request` | `` `.operations_pb2.CancelOperationRequest` `` The request object. Request message for `CancelOperation` method. |
| `retry` | `google.api_core.retry.Retry` Designation of what errors, if any, should be retried. |
| `timeout` | `float` The timeout for this request. |
| `metadata` | `Sequence[Tuple[str, Union[str, bytes]]]` Key/value pairs which should be sent along with the request as metadata. Normally, each value must be of type `str`, but for metadata keys ending with the suffix `-bin`, the corresponding values must be of type `bytes`. |

### common_billing_account_path

Returns a fully-qualified billing_account string.

### common_folder_path

    common_folder_path(folder: str) -> str
