how can i debug and change the source code？

[Ecthlion]

I'm sorry that this question may be childish. I am a new graduate student and my research group wants to study reasoning frameworks in a new direction. Therefore, I tried to learn sglang, but after reading the documentation and downloading and installing sglang, I don't know how to start a service debug and how to modify the code. I would like to know if there are similar textbooks or related documentation for lightllm that can teach me how to debug and modify the framework. I'm sorry that this question may be too naive, but I really don't know how to get started. Sorry.

If you want to develop or debug sglang, first of all, you may need some GPU machines. Secondly, it is recommended to use vscode. You can refer to Dev Guide, or refer to Build From Source to learn how to build SGLang.

Thank you very much for your reply! I have a server with 4 h800 , and I have tried running distserve experiments. I also built sglang from the source code according to the official documentation. However, I am confused about how to further understand what each part of sglang is doing and which code corresponds to which stages in the big model inference. This is my first time reading large-scale engineering code, and I don't know how to start. In fact, I don't know if this question is appropriate. If you have any suggestions, I would be very grateful. Thank you again for your response.
