How to understand Prometheus query 

http_requests_total{environment="testing",method="GET"} = 1
http_requests_total{environment="development",method="GET"} = 2
http_requests_total{environment="staging",method="GET"} = 1

Nếu bạn muốn hiển thị 1 metric là tổng số request GET thì chỉ cần đơn giản thực hiện query sau

sum (http_requests_total{method="GET"}) 


sum (http_requests_total{method="GET"}) without(environment)

sum (http_requests_total{method="GET"}) by(method)

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!
