TFE_DeleteTensorHandle(retval);

  // Custom device: inputs in different custom devices fails.
  matmul.reset(MatMulOp(context.get(), hcustom0.get(), hcustom1.get()));
  num_retvals = 1;
  TFE_Execute(matmul.get(), &retval, &num_retvals, status.get());
  ASSERT_NE(TF_OK, TF_GetCode(status.get()));
  ASSERT_TRUE(absl::StrContains(TF_Message(status.get()), custom0));

In this case, you can return the file path directly from your *path operation* function.

## Custom response class

You can create your own custom response class, inheriting from `Response` and using it.

For example, let's say that you want to use <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>, but with some custom settings not used in the included `ORJSONResponse` class.

Mas se você passasse uma `HTMLResponse` em `response_class` também, o **FastAPI** saberia como documentar isso no OpenAPI e na documentação interativa como um HTML com `text/html`:

## Respostas disponíveis

Aqui estão algumas dos tipos de resposta disponíveis.

しかし、一方では `response_class` に `HTMLResponse` を渡しているため、 **FastAPI** はOpenAPIや対話的ドキュメントでHTMLとして `text/html` でドキュメント化する方法を知っています。

## 利用可能なレスポンス

以下が利用可能なレスポンスの一部です。

`Response` を使って他の何かを返せますし、カスタムのサブクラスも作れることを覚えておいてください。

/// note | "技術詳細"

`from starlette.responses import HTMLResponse` も利用できます。

Aber da Sie die `HTMLResponse` auch in der `response_class` übergeben haben, weiß **FastAPI**, dass sie in OpenAPI und der interaktiven Dokumentation als HTML mit `text/html` zu dokumentieren ist:
