/// tip | 提示

`{"name", "description"}` 语法创建一个包含这两个值的 `set`。

等同于 `set(["name", "description"])`。

///

#### 使用 `list` 而不是 `set` { #using-lists-instead-of-sets }

如果你忘记使用 `set` 而是使用了 `list` 或 `tuple`，FastAPI 仍会将其转换为 `set` 并正常工作：

{* ../../docs_src/response_model/tutorial006_py310.py hl[29,35] *}

## 总结 { #recap }

使用*路径操作装饰器*的 `response_model` 参数来定义响应模型，尤其是确保私有数据被过滤掉。

// - a string representing the tracing implementation: "mlir" or "graphdef".
// - a boolean that when true enables TFRT as the execution engine.

        and `audio_dataset_from_directory`, to be used with the
        `validation_split` argument, for returning both dataset splits at once,
        as a tuple.
    *   Added `tf.keras.utils.split_dataset` utility to split a `Dataset` object
        or a list/tuple of arrays into two `Dataset` objects (e.g. train/test).
    *   Added step granularity to `BackupAndRestore` callback for handling

	    * Note: this fixes some issues with the previous implementation of metrics for disks:

	      * Time duration tracked was of the initial API call, not the entire operation.

	      * Metrics label tuple would have resulted in many independent histograms stored, one for each disk. (Did not aggregate well).
