Reason: With an unknown wire type, it is no longer possible to infer the data length, so the subsequent data can no longer be interpreted.翻译

原因:使用未知的 Wire Type 就无法推断数据的长度,因此后续的数据就无法解析。这句话的意思是,如果使用未知的 Wire Type,那么就无法确定数据的类型和长度信息,从而无法正确地解析后续的数据。在数据传输过程中,正确地解析数据是非常重要的,否则就会导致数据传输的错误和不可预测的结果。因此,在使用数据传输协议时,必须确保使用已知的 Wire Type,以便能够正确地解析数据的类型和长度信息,从而保证数据传输的正确性和可靠性。

In Java 7, it is possible to write ArrayList<>, for example, with no type specified for the elements. Give an example of a situation in which this is allowed and explain why it is allowed?
In Java 7 and later versions, it is possible to use the diamond operator `<>` to specify the type of a generic class with the type inference feature. For example, instead of writing `ArrayList<String>`, we can write `new ArrayList<>()` and the compiler will infer that it is an `ArrayList<String>` based on the context.
Here is an example of how the diamond operator can be used:
```
List<String> list = new ArrayList<>();
list.add("apple");
list.add("banana");
List<String> copy = new ArrayList<>(list); // diamond operator used for type inference
```
In this example, the `ArrayList` constructor is called with no type specified for the elements. However, the compiler is able to infer the type of the `ArrayList` based on the type of the `list` variable, which is a `List<String>`. Therefore, the `copy` variable is also inferred to be a `List<String>`.
The diamond operator is allowed in situations where the type of the generic class can be inferred from the context. This includes cases where the type is specified in the variable declaration or method signature, or where the generic class is being used in a method call with an argument of a specific type. By allowing the diamond operator, Java reduces the amount of boilerplate code needed to use generic classes and makes the code more concise and readable.

这个错误提示是因为缺少Paddle Inference库。您需要安装PaddlePaddle和Paddle Inference,或者确保已将其正确地添加到系统路径中。
如果您尚未安装PaddlePaddle和Paddle Inference,请按照以下步骤进行安装:
1. 安装PaddlePaddle
可以参考PaddlePaddle官网的安装指南进行安装:[https://www.paddlepaddle.org.cn/install/quick](https://www.paddlepaddle.org.cn/install/quick)
2. 安装Paddle Inference
可以从PaddlePaddle官网下载对应版本的Paddle Inference安装包:[https://www.paddlepaddle.org.cn/documentation/docs/zh/advanced_guide/inference_deployment/inference/build_and_install_lib_cn.html](https://www.paddlepaddle.org.cn/documentation/docs/zh/advanced_guide/inference_deployment/inference/build_and_install_lib_cn.html)
安装完成后,将Paddle Inference库添加到系统路径中,例如:
```
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/paddle_inference/lib
```
或者将Paddle Inference库添加到/etc/ld.so.conf中,并使用以下命令更新缓存:
```
sudo ldconfig
```
