Linux command line

1. uname -m
Uname
uname (short for unix name) is a computer program in Unix and Unix-like computer operating systems that prints the name, version and other details about the current machine and the operating system running on it. The uname system call and command appeared for the first time in PWB/UNIX. Both are specified by POSIX.

2. Check running service in Linux

for example check docker.service
//Run this command on Linux systems not using Systemd
$ service docker status
docker start/running, process 29393


//Run this command on Linux systems that are using Systemd
$ systemctl is-active docker
active

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!
