**The Compilation Encountered This Issue: How to Resolve It?**

Introduction

When working with complex projects, especially those involving deep learning frameworks like TensorRT, it's not uncommon to encounter compilation issues. In this article, we'll delve into a specific issue that arises during the compilation process and provide a step-by-step guide on how to resolve it.

Problem Description

The compilation issue we're dealing with is related to the use of deprecated classes in the TensorRT library. Specifically, the IPluginV2 class is deprecated, and its usage is causing compilation errors. Additionally, there are errors related to the use of std::optional in the option.hpp file.

Compilation Errors

The compilation errors are as follows:

/third_party/TensorRT-8.6.1.6/include/NvInferRuntimePlugin.h:97:22: note: declared here
   97 | class TRT_DEPRECATED IPluginV2
      |                      ^~~~~~~~~
In file included from /root/Deploy/TensorRT-YOLO/deploy/core/core.hpp:13,
                 from /root/Deploy/TensorRT-YOLO/deploy/infer/backend.cpp:14:
/third_party/TensorRT-8.6.1.6/include/NvInferPlugin.h:105:77: warning: ‘IPluginV2’ is deprecated [-Wdeprecated-declarations]

      |                                                                             ^
...

Resolving the Issue

To resolve this issue, we need to address two main problems:

Deprecated Classes: The IPluginV2 class is deprecated, and its usage is causing compilation errors. We need to update the code to use the latest version of the TensorRT library, which should not include deprecated classes.
std::optional Errors: There are errors related to the use of std::optional in the option.hpp file. We need to fix these errors by updating the code to use the correct syntax for std::optional.

Step 1: Update TensorRT Library

To resolve the issue with deprecated classes, we need to update the TensorRT library to the latest version. This can be done by:

Checking the TensorRT documentation for the latest version.
Updating the TensorRT library to the latest version using the package manager or by downloading the latest version from the TensorRT website.
Rebuilding the project using the updated TensorRT library.

Step 2: Fix `std::optional` Errors

To resolve the errors related to std::optional, we need to fix the code in the option.hpp file. Specifically, we need to update the code to use the correct syntax for std::optional.

Check the option.hpp file for errors related to std::optional.
Update the code to use the correct syntax for std::optional.
Rebuild the project to ensure that the errors are resolved.

Conclusion

In this article, we've discussed a specific compilation issue that arises during the compilation process of a project using the TensorRT library. We've provided a step-by-step guide on how to resolve the issue by updating the TensorRT library and fixing errors related to std::optional. By following these steps, developers can resolve compilation issues and ensure that their projects compile successfully.

Additional Tips

Always check the TensorRT documentation for the latest version and updates.
Use the latest version of the TensorRT library to avoid deprecated classes and other issues.
Regularly rebuild the project to ensure that errors are resolved and the project compiles successfully.

Q: What is the cause of the compilation issue with TensorRT?

A: The compilation issue with TensorRT is caused by the use of deprecated classes in the TensorRT library. Specifically, the IPluginV2 class is deprecated, and its usage is causing compilation errors.

Q: How can I resolve the issue with deprecated classes?

A: To resolve the issue with deprecated classes, you need to update the TensorRT library to the latest version. This can be done by checking the TensorRT documentation for the latest version, updating the TensorRT library using the package manager or by downloading the latest version from the TensorRT website, and rebuilding the project using the updated TensorRT library.

Q: What are the common errors related to `std::optional` in the `option.hpp` file?

A: The common errors related to std::optional in the option.hpp file are:

std::optional<int2> input_shape; is not a valid declaration.
input_shape = make_int2(height, width); is not a valid assignment.

Q: How can I fix the errors related to `std::optional`?

A: To fix the errors related to std::optional, you need to update the code in the option.hpp file to use the correct syntax for std::optional. Specifically, you need to use the std::optional constructor to create an instance of std::optional and then assign a value to it.

Q: What are the benefits of using the latest version of the TensorRT library?

A: The benefits of using the latest version of the TensorRT library are:

Avoid deprecated classes and other issues.
Take advantage of new features and improvements.
Ensure compatibility with the latest versions of other libraries and frameworks.

Q: How can I ensure that my project compiles successfully?

A: To ensure that your project compiles successfully, you need to:

Regularly rebuild the project to ensure that errors are resolved.
Use the latest version of the TensorRT library.
