Bạn đã từng nghĩ về AOP trong Spring

Làm thế nào nó hoạt động được

hoặc bạn từng nghĩ viết hàm loging cho method một class nào đó mà không cần sửa class đó

hãy nghĩ tới CGlib


ví dụ bạn có một class như bên dưới và có 2 methods

public class PersonService {
    public String sayHello(String name) {
        return "Hello " + name;
    }

    public Integer lengthOfName(String name) {
        return name.length();
    }
}

Fixing the DeepSpeed Import Error While Fine-Tuning the Qwen Model

While fine-tuning the Qwen model, I encountered an error in the finetune.py script: ImportError : cannot import name 'deepspeed' from 'transformers.deepspeed' After some investigation, I discovered the issue stems from a recent update in the Transformers library. The transformers.deepspeed module has been deprecated and replaced by transformers.integrations . To fix this, you need to update the import statement in your script. The Fix Replace this: from transformers.deepspeed import deepspeed With this: from transformers.integrations import deepspeed This small change resolved the error, allowing the fine-tuning process to proceed smoothly. Additional Resources For more details, refer to the discussion in the official Transformers GitHub repository: Issue #34582 Remember to keep your library versions up-to-date to avoid similar issues in the future!
