That should make more sense now. ✨

All that is what powers FastAPI (through Starlette) and what makes it have such an impressive performance.

You can probably skip this.

These are very technical details of how **FastAPI** works underneath.

In Python 3.10 there's also a **new syntax** where you can put the possible types separated by a <abbr title='also called "bitwise or operator", but that meaning is not relevant here'>vertical bar (`|`)</abbr>.

Trong Python 3.10 cũng có một **cú pháp mới** mà bạn có thể đặt những kiểu giá trị khả thi phân cách bởi một dấu <abbr title='cũng được gọi là "toán tử nhị phân"'>sổ dọc (`|`)</abbr>.

// You must use TF_AddInput() for the first input (since it takes a
// single tensor), and TF_AddInputList() for the second input (since
// it takes a list, even if you were to pass a list with a single

//   TF_OperationDescription* desc = TF_NewOperation(graph, "Concat", "c");
//   TF_Output concat_dim_input = {...};
//   TF_AddInput(desc, concat_dim_input);
